Chart understanding, infographic question answering and chart-to-code

Each infographic exposes its chart families in slot order and, where recoverable, the data table the charts were drawn from. Text is live, so no OCR step is needed to build supervision.

Fields that carry the supervision

  • chart_families[]
  • data_table
  • texts[]
  • headline
  • subject
  • sector

A training recipe

Generate chart-QA pairs from data_table and texts[] without annotation cost. Fine-tune a vision-language model on png_448 with the generated answers.

Evaluation

Buyers typically run DINO, SSIM, LPIPS and PSNR for image-to-SVG; FID, CLIP text-image score and render-validity rate for text-to-SVG; alignment and overlap metrics for layout; and IoU over room polygons for floor plans. A held-out evaluation set stratified by complexity is specified in the order, so these numbers stay comparable between runs.
