ArXi:2405.13580v2 Announce Type: replace Chart summarization is a crucial task for blind and visually impaired individuals as it is their primary means of accessing and interpreting graphical data.

Many chart analysis methods, however, produce brief, unstructured responses that may contain significant hallucinations, affecting their reliability for blind people.
