Chart-FR1: Focus-Driven Reasoning for Dense Charts

ai-technology · 2026-05-06

The introduction of Chart-FR1 aims to enhance the effectiveness of multimodal large language models (MLLMs) when dealing with high information density (HID) charts. These charts, characterized by numerous subplots, legends, and intricate annotations, present three primary difficulties: insufficient fine-grained perception that leads to missing vital visual signals, excessive visual redundancy that hampers reasoning, and a deficiency in adaptive deep reasoning. To tackle these issues, Chart-FR1 employs Focus-CoT, a visual focusing chain-of-thought that connects reasoning processes to essential visual elements such as local image areas and OCR signals. This model improves perception, efficiency in focus, and adaptive deep reasoning for HID charts. The findings are detailed in arXiv paper 2605.01882v1.
