Abstract

from arXiv · show

Visualizations play a crucial part in effective communication of concepts and information. Recent advances in reasoning and retrieval augmented generation have enabled Large Language Models (LLMs) to perform deep research and generate comprehensive reports. Despite its progress, existing deep research frameworks primarily focus on generating text-only content, leaving the automated generation of interleaved texts and visualizations underexplored. This novel task poses key challenges in designing informative visualizations and effectively integrating them with text reports. To address these challenges, we propose Formal Description of Visualization (FDV), a structured textual representation of charts that enables LLMs to learn from and generate diverse, high-quality visualizations. Building on this representation, we introduce Multimodal DeepResearcher, an agentic framework that decomposes the task into four stages: (1) researching, (2) exemplar report textualization, (3) planning, and (4) multimodal report generation. For the evaluation of generated multimodal reports, we develop MultimodalReportBench, which contains 100 diverse topics served as inputs along with 5 dedicated metrics. Extensive experiments across models and evaluation methods demonstrate the effectiveness of Multimodal DeepResearcher. Notably, utilizing the same Claude 3.7 Sonnet model, Multimodal DeepResearcher achieves an 82% overall win rate over the baseline method.

Introduction

Deep-research systems largely generate text-only reports, while integrating charts with text remains challenging without a suitable representation. The paper introduces FDV and Multimodal DeepResearcher for generating interleaved reports, and reports an 82% overall win rate over its baseline with Claude 3.7 Sonnet.

Method

Multimodal DeepResearcher turns a topic and multimodal exemplars into an interleaved report through research, exemplar textualization, planning, and report generation. FDV represents chart designs in text, while the final stage drafts report text, codes charts, and refines them iteratively.

Method

  • The task is to generate a multimodal report for a topic, using interleaved text-and-chart exemplar reports as a model.The framework decomposes this task into researching, exemplar textualization, planning, and multimodal report generation.Source: Method · p. 3

Researching

  • Iterative research searches for topic-relevant keywords, retrieves webpages, synthesizes learnings and references, and formulates a question for the next research cycle.After multiple rounds, it produces a final list of learnings and references.Source: Researching · pp. 3–4

Exemplar Textualization

  • FDV textualizes charts through four perspectives: layout, plotting scale, data, and marks.The framework extracts FDV from exemplar charts to replace them in textual reports; coding can reconstruct a visualization from its FDV.Source: Exemplar Textualization · p. 4

Planning

  • Planning builds a hierarchical report outline from the topic and learnings, and creates a visualization style guide from the textualized exemplars.The guide controls overall visualization style, including palette and font hierarchy.Source: Planning · pp. 4–5

Final Report Generation

  • The final stage uses learnings, textual exemplars, an outline, and a style guide to draft text with FDV chart placeholders, then implements the charts in code.The paper uses D3.js because the designs may exceed the expressive capabilities of typical declarative visualization libraries.Source: Final Report Generation · p. 5
  • An actor-critic loop uses console messages and multimodal visual feedback to revise chart code, stopping when the critic is satisfied or after three retries.When refinement produces multiple candidates, the critic selects the final chart from the last two.Source: Final Report Generation · p. 5

Experiments

The experiments compare Multimodal DeepResearcher with an adapted DataNarrative baseline on multimodal reports and charts. Automatic evaluation reports an 82% overall win rate with Claude 3.7 Sonnet, while human evaluation on 20 topics reports a 100% overall win rate.

Data Selection

  • MultimodalReportBench contains 100 real-world topics across 10 categories, with six non-overlapping multimodal reports used as in-context exemplars.The topics were curated from public websites featuring human-created multimodal reports.Source: Data Selection · p. 5

Baseline Selection

  • The baseline adapts DataNarrative to use the framework's research learnings and plans instead of tables, then applies generate-verify-refine and the same chart-generation pipeline.The paper selects it because its task requires report generation from scratch, unlike single-chart or human-interaction settings.Source: Baseline Selection · pp. 5–6

Framework Implementation

  • The implementation uses GPT-4o-mini for research and planning, Claude 3.7 Sonnet for exemplar textualization, and proprietary or open-source model configurations for final generation.The open-source configuration uses Qwen3-235B-A22B and Qwen2.5-VL-72B-Instruct.Source: Framework Implementation · p. 6

Automatic Report Evaluation

  • Automatic report evaluation assesses report text and visualizations using five criteria: informativeness and depth, coherence and organization, verifiability, visualization quality, and visualization consistency.Source: Automatic Report Evaluation · p. 6
  • 82% overall win rate is reported for Multimodal DeepResearcher with Claude 3.7 Sonnet, which consistently outperforms DataNarrative across proprietary and open-source configurations.With open-source models, the reported win rate is 55%; the advantage is more pronounced with Claude 3.7 Sonnet.Source: Automatic Report Evaluation · p. 6, Table 1 · p. 7

Human Evaluation

  • Human evaluation on 20 randomly selected topics gives Multimodal DeepResearcher a 100% overall win rate against DataNarrative.Five annotators compared reports generated with Claude 3.7 Sonnet; their agreement with GPT-4.1 was 80%.Source: Human Evaluation · p. 6, Table 2 · p. 7

Chart Evaluation

  • Chart-level evaluation finds Multimodal DeepResearcher consistently outperforms DataNarrative, with particularly notable improvements in layout and aesthetics.The five chart metrics are readability, layout, aesthetics, data faithfulness, and goal compliance.Source: Chart Evaluation · p. 7, Table 3 · p. 7

Ablation Studies

  • Removing exemplar learning yields a 70% lose rate, direct generation without planning leads to 85%, and removing chart refinement loses in 80% of cases.The ablations compare each variant with the complete framework on a random subset of 20 topics.Source: Ablation Studies · p. 7, Table 4 · p. 7

Analysis

Multimodal DeepResearcher produces a more diverse chart mix than DataNarrative, while both generate similar numbers of charts per report. The analysis also identifies overlapping elements and hallucinated data as chart errors, and reports a substantial generation-time overhead associated with refinement.

Visualization Analysis

  • 15 flowcharts and 18 dashboards versus DataNarrative’s 2 and 1, plus 280 “Others” charts versus 96, show a more diverse chart mix.The comparison appears in Figure 4; both systems also prioritize basic line and bar charts, while Multimodal DeepResearcher generates more sophisticated visualizations.Source: Visualization Analysis · pp. 7–8, Figure 4 · p. 8

Error Analysis

  • Element overlap is the most prevalent chart error, linked to difficult spatial positioning without real-time visual feedback.The passage attributes overlap to excessive FDV information in limited space and suboptimal placement of legends, labels, and annotations.Source: Error Analysis · p. 8
  • Models sometimes hallucinate visualization data when data is insufficient or unavailable, despite instructions not to fabricate it.One example marks regions with inadequate data in red on a choropleth map to indicate a metric decline.Source: Error Analysis · p. 8

Efficiency Analysis

  • After filtering network-affected instances, average report generation takes 767.20 seconds, compared with DataNarrative’s 372.94 seconds.Charts are refined for at most 3 iterations; refinement accounts for most execution time through browser interaction, multimodal evaluation, and code regeneration.Source: Efficiency Analysis · p. 8
  • Iterative chart refinement significantly enhances overall report quality but introduces computational overhead.The authors plan to explore more precise critique mechanisms.Source: Efficiency Analysis · p. 8

Conclusion

The paper presents FDV as a structured chart representation and builds Multimodal DeepResearcher to generate multimodal reports from scratch. Its supporting process researches a topic, textualizes expert exemplars, plans report content and style, and generates the interleaved report; the authors note remaining challenges in visualization quality, hallucination, and efficiency.

Conclusion

  • The authors conclude that Multimodal DeepResearcher generates multimodal reports from scratch, while visualization quality, hallucination, and utility-efficiency trade-offs remain challenges.The conclusion says extensive automatic and human evaluations confirm the framework’s efficacy.Source: Conclusion · p. 8

Comparative Cost-Effectiveness

  • No single solution fits every setting: low-income countries favor collection, segregation, informal-sector support, and awareness, while middle-income settings favor mechanical recycling and EPR.High-income countries show stronger results from chemical recycling and comprehensive policy frameworks; the framework calls for tailoring integrated approaches to local economic contexts.Source: Comparative Cost-Effectiveness · pp. 41–42

Mapping Investment Needs and Financing Gaps

  • Mismanaged plastic waste is projected to exceed 250 million metric tons annually by 2040, requiring USD 1.64 trillion in redirected financial flows toward circularity.Against estimated needs exceeding US $30 billion annually, 2021 official development finance commitments for solid waste management totaled only US $1.8 billion, leaving a gap above US $28 billion per year.Source: Mapping Investment Needs and Financing… · p. 42, Current Financing Landscape · p. 42

Lessons from Climate Finance
