Merged summary
TL;DR - ArtChart is a framework and benchmark for generating stylized charts while preserving numerical geometry, exact text, label-mark alignment, and readability. It matters because current image models often sacrifice mathematical integrity for visual appeal.
- Uses text-free grayscale layouts to condition generation and preserve chart structure.
- Applies reinforcement learning with OCR, layout-quality, and aesthetic rewards.
- Uses multi-expert distillation to mitigate conflicts among optimization rewards.
- Introduces a bilingual 2K-prompt benchmark and six-axis evaluation suite spanning four chart types.
