Chart-FR1: Visual Focus-Driven Fine-Grained Reasoning on Dense Charts

arXiv CS.LG

ArXi:2605.01882v1 Announce Type: cross Multimodal large language models (MLLMs) have shown considerable potential in chart understanding and reasoning tasks. However, they still struggle with high information density (HID) charts characterized by multiple subplots, legends, and dense annotations due to three major challenges: (1) limited fine-grained perception results in the omission of critical visual cues; (2) redundant or noisy visual information undermines the performance of multimodal reasoning; (3) lack of adaptive deep reasoning relative to the amount of visual information.
