Abstract (Summary)
Chart2SVG reconstructs editable vector charts from raster inputs. Its vision-language model learns chart elements and their roles using the Beagle+ training collection. Training also evaluates rendered results to improve the appearance and organization of generated SVGs. A graph representation records relationships among chart components, allowing subsequent operations to preserve those relationships. The project demonstrates retrieving values, selecting marks, changing scales, transforming chart types, and adapting an existing layout to another dataset.
