MultiVis-Agent: A Multi-Agent Framework with Logic Rules for Reliable and Comprehensive Cross-Modal Data Visualization
Abstract: Real-world visualization tasks involve complex, multi-modal requirements that extend beyond simple text-to-chart generation, requiring reference images, code examples, and iterative refinement. Current systems exhibit fundamental limitations: single-modality input, one-shot generation, and rigid workflows. While LLM-based approaches show potential for these complex requirements, they introduce reliability challenges including catastrophic failures and infinite loop susceptibility. To address this gap, we propose MultiVis-Agent, a logic rule-enhanced multi-agent framework for reliable multi-modal and multi-scenario visualization generation. Our approach introduces a four-layer logic rule framework that provides mathematical guarantees for system reliability while maintaining flexibility. Unlike traditional rule-based systems, our logic rules are mathematical constraints that guide LLM reasoning rather than replacing it. We formalize the MultiVis task spanning four scenarios from basic generation to iterative refinement, and develop MultiVis-Bench, a benchmark with over 1,000 cases for multi-modal visualization evaluation. Extensive experiments demonstrate that our approach achieves 75.63% visualization score on challenging tasks, significantly outperforming baselines (57.54-62.79%), with task completion rates of 99.58% and code execution success rates of 94.56% (vs. 74.48% and 65.10% without logic rules), successfully addressing both complexity and reliability challenges in automated visualization generation.
Summary
- The paper introduces MultiVis-Agent, a multi-agent framework that applies formal logic rules to ensure reliable, iterative, and comprehensive cross-modal data visualization.

MultiVis-Agent: Robust Multi-Agent Framework for Cross-Modal Data Visualization
Motivation and Problem Setting
Automated data visualization systems frequently fail in authentic analytical scenarios due to inherent complexity in user requirements, which involve multi-modal inputs (natural language, database schema, reference images, reference code) and iterative refinement demands. Existing Text-to-Vis approaches are typically constrained to one-shot, single-modality paradigms and rigid workflows, making them unsuitable for tasks such as style adaptation, code translation, and progressive enhancements. LLM-based workflows further introduce reliability challenges—catastrophic errors, uncontrolled error propagation, and infinite loop susceptibility—precluding robust deployment in production settings.
Figure 1: Real-world visualization tasks require multi-modal inputs and iterative refinement. Current Text-to-Vis systems fail to support these scenarios.
MultiVis Formulation and MultiVis-Bench
MultiVis generalizes visualization generation to a comprehensive task family, spanning four scenarios:
- Basic Generation: Traditional text and tabular data inputs.
- Image-Referenced Generation: Style and layout cues communicated via images.
- Code-Referenced Generation: Code examples serving as implementation guides.
- Iterative Refinement: Feedback-driven adjustment to pre-existing code.
This task definition acknowledges distinct mappings and architectural needs for each scenario, e.g., vision-language reasoning in image referencing and semantic code translation for cross-library adaptation.
MultiVis-Bench, constructed with LLM assistance and rigorous expert validation, supports over 1,000 high-quality cases distributed across these scenarios, encompassing 127 chart types and 141 complex databases. It uniquely supports direct multi-modal inputs with executable Python code outputs, enabling differentiated assessment of structure, semantics, and perceptual efficacy for visualization.
MultiVis-Agent Framework: Architecture and Logic Rule Enhancement
Centralized Multi-Agent Design
MultiVis-Agent implements a coordinator-centric architecture featuring three specialized agents:
- Database Query Agent (DQ Agent): SQL query generation, data extraction.
- Visualization Implementation Agent (Vis Agent): Altair code synthesis and refinement, cross-modal comprehension (e.g., Gemini-2.0-Flash VLM processing of visual styles).
- Validation Evaluation Agent (VE Agent): Technical and perceptual correctness assessment leveraging advanced VLMs, automated feedback for iterative correction.
These agents interact through a Coordinator, governed by formally specified logic rules to suppress error propagation, enforce parameter safety, and guarantee workflow termination.

Four-Layer Logic Rule Framework
The core innovation lies in the integration of a four-layer logic rule framework, which mathematically constrains agentic reasoning and execution:
- CR (Coordination): Deterministic scenario/task classification and prerequisite validation; ensures explicit, non-ambiguous routing across scenarios and tools.
- TE (Tool Execution): Enforces parameter ranges, code environment standardization, and controlled reference processing to prevent unsafe executions.
- EH (Error Handling): Structures error detection, classification, and recovery; mitigates cascading failures by enforcing bounded recovery steps.
- RC (ReAct Control): Manages loop termination, response formatting, and model selection; provides formal iteration bounds () that prevent infinite cycles.
The framework applies mathematically formalized guarantees (Theorems 1–4) for parameter safety, bounded error recovery, loop termination, and overall system reliability. Notably, logic rules do not supplant LLM content generation but instead operate as behavioral constraints and validators, segregating control decisions from generative flexibility and eliminating catastrophic LLM failure modes.
Dual-Layer Evaluation Methodology
The evaluation regime fuses low-level structural metrics and high-level perceptual metrics:
- Structural metrics: Chart type, data mapping, encoding consistency, interaction correctness, configuration, and data transformation, quantified via normalized scores.
- Perceptual metrics: VLM-driven assessment of chart appropriateness, layout, text clarity, data representation, styling, and global interpretability, weighted by domain-critical factors.
The final score, a weighted fusion ( in experiments), provides rigorous technical and visual performance evaluation, essential for production deployment.
Empirical Results
MultiVis-Agent demonstrates robust superiority across all scenarios and modalities. On MultiVis-Bench:
- Visualization Quality: Achieves in Image-Referenced Generation, outperforming LLM Workflow () and Instructing LLM (). Comparable gains materialize in Basic and Code-Referenced tasks and persist across both Gemini-2.0-Flash and GPT-4o backbones.
- Task Success Rate: Exceeds for generation tasks, with code execution success at —contrasting sharply with and for ablations without logic rules.
- Component Analysis: Ablation studies quantify the impact of each module; removal of logic rules diminishes performance by 18–32pp (image and code referencing). VE Agent and DB Agent are indispensable for quality assurance and data validity.
Reliability and Ablation
The mathematical constraint framework provides provable reliability improvements (20–32pp uplift for completion and execution rates). Component analysis evidences the criticality of logic rules and agent specialization, as single-agent code generation variants consistently underperform. The design allows complexity matching, optimizing for both focused refinement and complex multi-modal generation.
Qualitative Assessment
MultiVis-Agent reliably handles visually and semantically intricate instructions, e.g., conditional formatting driven by style cues in reference images, outperforming baselines which either misinterpret requirements or generate syntactically invalid code. The centralized framework systematically recovers from failure modes endemic to LLM workflows, eliminating intermediate representation bottlenecks and error propagation.

Theoretical and Practical Implications
This work reifies a new paradigm for agentic system design in data visualization, blending statistical LLM modeling with mathematical system control. It thoroughly addresses the limitations of prior LLM, multi-agent, and pipeline-based architectures, establishing a blueprint for reliable, scalable, and adaptable cross-modal AI visualization systems. Future directions include application to multi-view, dashboard, and interface synthesis tasks; incorporation of more expressive visual grammars; and extension to federated analytics environments and agentic orchestration under real-time or streaming constraints.
Conclusion
MultiVis-Agent exemplifies a scalable, reliable, logic rule-enhanced multi-agent system for comprehensive, cross-modal, and iterative visualization generation (2601.18320). It establishes mathematical guarantees for robustness and error recovery, delivers empirically validated performance superiority, and charts a clear trajectory for future agentic AI systems in data visualization and analytic interface synthesis.

Overview: What this paper is about
This paper introduces MultiVis-Agent, a smart AI system that can turn different kinds of inputs—like text, pictures of charts, example code, and even existing chart code—into working, good-looking data visualizations. It’s designed for real-world use where people often need to tweak charts step by step, not just get a one-shot result. The big idea is to combine the creativity of AI with strict “logic rules” that act like guardrails, so the system stays reliable, avoids getting stuck in loops, and doesn’t crash.
Key questions the paper asks
- How can we build an AI system that understands many types of inputs (text, images, code) for making charts?
- How can it safely improve charts over several rounds of feedback without breaking?
- Can we add clear rules so the system has mathematical guarantees it will stop, recover from errors, and run safely?
- How do we fairly test such a system across different real-world situations?
How the researchers approached the problem
A team of smart helpers (agents)
Think of MultiVis-Agent like a team with a coach:
- The Coordinator Agent is the coach. It looks at the task and decides who should do what.
- The Database Query Agent is the data expert. It finds the right data by writing SQL (the language for databases).
- The Visualization Implementation Agent is the code writer. It creates or edits chart code (in Python using Altair).
- The Validation and Evaluation Agent is the checker. It runs the code and evaluates whether the chart matches the request and looks clear.
These agents talk and work in cycles: get data → write chart code → check it → refine it. This setup helps the system handle complex requests and fix mistakes step by step.
The four logic rules: guardrails that keep things safe
To avoid common AI failures (like endless loops, bad parameters, or brittle workflows), the system follows four layers of rules. You can think of them like the rules of a game that keep play fair and safe:
- Task classification: The coach decides exactly what kind of task it is.
- Basic text request
- Text + reference image
- Text + reference code
- Edit existing chart code
- Parameter limits: Tools only run with safe inputs (like keeping numbers within allowed ranges).
- Error recovery: When something goes wrong (a code error or bad input), the system identifies the type of error and follows a plan to fix it.
- Loop termination: There’s a strict stop rule (a maximum number of attempts), so the system won’t get stuck repeating forever.
These rules don’t replace the AI’s thinking. Instead, they set boundaries so the AI stays dependable while still being flexible.
The MultiVis-Bench test set
To fairly test the system, the authors built a new benchmark called MultiVis-Bench with 1,202 examples. It covers four realistic scenarios and uses real databases and executable Python chart code. This makes testing end-to-end: the system must produce code that actually runs and makes the right chart.
Here are the four scenarios they test:
- Basic Generation: Make a chart from text + data.
- Image-Referenced Generation: Make a chart that matches a style shown in a picture.
- Code-Referenced Generation: Adapt a chart using example code as a guide.
- Iterative Refinement: Improve an existing chart based on feedback (like “rotate labels” or “add a title”).
Main findings: What worked and why it’s important
The system did much better than other methods, especially on tougher tasks:
- Chart quality scores were higher: about 75.63% in challenging image-guided tasks versus 57.54–62.79% for baselines.
- It almost always finished the job: 99.58% task completion with the logic rules, compared to 74.48% without them.
- Its code ran successfully most of the time: 94.56% execution success, compared to 65.10% without the rules.
In short, adding the four logic rule layers made the system both smarter and safer. It could handle multi-modal inputs and refine charts over several steps, while avoiding common AI pitfalls like crashes or infinite loops.
Why it matters and what could come next
Many people—from students to data analysts—need charts that look good, match a specific style, and are easy to adjust. MultiVis-Agent shows that you can combine AI’s creativity with strict safety rules to make a reliable assistant for real-world visualization work.
Potential impacts:
- Better tools for data analysis that understand multiple input types (text, images, example code).
- Smarter chart editors that safely refine visualizations over time.
- A foundation for reliable, rule-guided AI systems in other areas where consistency and safety matter (like coding assistants, data cleaning, or report generation).
Future steps could include supporting more chart libraries, handling even richer inputs (like interactive dashboards), and expanding the benchmark to cover more domains and styles.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a consolidated list of what remains missing, uncertain, or unexplored in the paper, phrased to be concrete and actionable for future research.
- Metric transparency: The paper reports a “visualization score” and task completion/execution success, but does not define the scoring rubric, measurement procedure, annotator protocol, inter-rater reliability, or the extent of automated versus human judgments. Future work should specify metric definitions, validation, and quality control.
- Image-to-style fidelity evaluation: While Image-Referenced Generation (IRG) is a core scenario, there is no quantitative method described for assessing style/layout/color fidelity to the reference image (e.g., structural similarity, palette matching, typography/alignment metrics). A standardized fidelity metric and benchmark annotations would strengthen claims.
- Vision modality details: The system’s mechanism for interpreting reference images (model choice, feature extraction pipeline, vision-language fusion strategy) is not described. Clarify the vision backbone, pre/post-processing, and how visual cues are encoded to guide code generation.
- Code-reference translation specifics: For Code-Referenced Generation (CRG), cross-library translation strategies (e.g., Matplotlib → Altair) are not formalized beyond LLM-driven adaptation. Provide explicit mapping patterns, semantic equivalence checks, and tests across diverse libraries (Altair, Matplotlib, Vega-Lite, Plotly).
- Output modality limitation: MultiVis-Bench outputs only executable Altair Python code. It remains unknown how well the framework generalizes to other visualization grammars and runtimes (Matplotlib, Vega-Lite, ggplot, D3/Observable). Extending outputs and evaluating cross-library generalization is needed.
- Dataset representativeness and scale: MultiVis-Bench has 1,202 examples and draws schemas from Spider, with 109 IRG cases and 233 CRG cases. Assess whether the dataset size and domain diversity sufficiently capture real-world complexity (messy schemas, heterogeneous data types, temporal/geospatial, high cardinality). Expand coverage and report domain distributions and difficulty strata.
- Real-world, human-in-the-loop validation: Iterative Refinement (IR) uses expert-crafted modification instructions; no live user study evaluates usability, iteration quality, satisfaction, or time-to-task metrics. Conduct controlled and field studies with analysts and developers.
- Ambiguity handling in NLQ: The paper acknowledges ambiguous queries but does not detail disambiguation strategies (e.g., clarification questions, schema-aware suggestions). Formalize and evaluate an ambiguity resolution protocol.
- Conflict resolution in multi-modal inputs: The deterministic priority ordering (D ≻ C ≻ B ≻ A) may ignore useful lower-priority cues or lead to suboptimal fusion when inputs conflict. Investigate multi-source fusion policies, conflict detection, and weighted integration that leverage all modalities.
- Error taxonomy completeness: EH rules assume a fixed set of error types (parameter, execution, parse, timeout), but real systems face more heterogeneity (e.g., data encoding issues, dependency/version mismatches, environment permissions, GPU/CPU resource limits). Extend taxonomy, recovery strategies, and empirical coverage.
- Termination bound rationale: The global iteration cap T_max = 10 is asserted but not justified or adapted to task complexity. Study the sensitivity of performance and reliability to T_max, and design adaptive termination policies that consider task difficulty and evaluation feedback.
- Formal guarantees assumptions: Proof sketches rely on bounded processing times, finite error sets, and reliable validation predicates; these are not formally verified or mechanized. Provide rigorous assumptions, formal models of LLM outputs, and, where feasible, mechanized proofs or runtime monitors to ensure guarantees hold.
- Enforcement mechanisms: RC/CR/TE/EH rules assume robust enforcement over LLM outputs (e.g., response format validation, prerequisite checks). Detail the exact parsers, validators, execution sandboxes, and how rule violations trigger overrides, including failure modes when LLMs deviate from expected formats.
- Security and sandboxing: Code execution “standardization” is mentioned, but the paper does not describe sandboxing, resource limits, I/O restrictions, dependency management, or injection defenses for SQL/code. Document security model and conduct penetration tests.
- Scalability and latency: The system’s throughput, end-to-end latency, and resource footprint (model calls, tool invocations, evaluation cycles) are not reported. Benchmark performance under load, and explore optimization (caching, tool selection policies, partial compilation, streaming).
- Database complexity coverage: The DQ agent tools are described, but there is no quantitative analysis of SQL complexity (joins, nested queries, window functions) or success on challenging schema features (weakly structured text fields, many-to-many relationships, schema drift). Add SQL difficulty tiers and report success per tier.
- Handling large and non-relational data: The approach focuses on SQLite relational tables. Extensions to big data backends (e.g., warehouses), non-relational sources (JSON, Parquet), and streaming/interactive data are unexplored. Evaluate scalability beyond local SQLite.
- Advanced visualization features: Support for interactivity, dashboards/multi-view compositions, tooltips, filters, linked brushing, theming, and accessibility (colorblind-safe palettes, font sizes) is not assessed. Expand benchmarks and metrics to cover interaction and accessibility.
- Cross-lingual generalization: All scenarios appear in English. Assess performance on NLQ and code comments across languages, including multilingual databases and locale-specific formats.
- Reproducibility of model dependencies: The system uses “Gemini-2.0-pro-exp” for dataset construction and unspecified LLM(s) at runtime. Report exact model versions, configurations, temperature/decoding settings, seeds, and costs; provide baselines with open models.
- Baseline fairness and transparency: The “LLM Workflow” and “Instructing LLM” baselines are not fully specified (architectures, prompt templates, iteration policies, tool access). Provide detailed baselines, ablation studies, and ensure identical external conditions where possible.
- Failure analysis: The paper reports aggregate gains but lacks qualitative analyses of failure modes (e.g., misinterpreted styles, incorrect encodings, schema misalignment). Include error case studies and actionable insights for improvement.
- Rule design and maintenance cost: The four-layer logic rules likely require manual specification, tuning, and updates. Quantify the engineering overhead, rule conflicts, and portability to other tasks; investigate automated rule induction/refinement.
- Model selection criteria: RC-Rule 3 depends on a compatibility function κ for choosing models based on content and URLs, but κ is undefined. Specify selection criteria, decision boundaries, and empirical gains from adaptive model routing.
- Integration with BI ecosystems: Real-world adoption often requires integration with existing tools (Tableau, Power BI, Superset) and workflows (versioning, collaboration). Explore connectors, export formats, and user interfaces for production deployment.
- Ethics and bias in visualization: Perceptual effectiveness is mentioned, but fairness/ethics (e.g., misleading encodings, bias amplification, deceptive scales) are not evaluated. Define ethical guidelines and audit procedures for generated charts.
- Licensing and dataset accessibility: Clarify licensing of curated images/code snippets, database redistribution rights, and potential legal constraints; provide dataset cards and documentation for responsible use.

Notes on Feasibility and Dependencies (common across applications)
- Model capabilities: High-quality, multimodal LLMs are needed to interpret images and code references; reliability depends on model latency/cost and access policies.
- Execution sandboxing: Safe, deterministic code execution with network/filesystem restrictions is critical to realize parameter safety and error recovery in production.
- Data connectors and governance: Secure, audited access to databases; role-based controls and PII/PHI handling for regulated sectors.
- Library coverage: The current system targets Altair and Matplotlib; broader adoption requires more libraries/grammars and domain-specific templates.
- Rule tuning and monitoring: Logic rules may need domain tuning (e.g., acceptable parameter ranges, termination thresholds). Observability is needed to catch edge cases and measure drift.
- IP and compliance: Using reference images/code implies licensing and attribution considerations; organizational policies must allow LLM-mediated tooling.
- Benchmark representativeness: MultiVis-Bench enables rigorous evaluation but should be complemented with domain datasets (e.g., clinical, financial) for transferability.
