ChartAnno - Implementation-Level Design Effectiveness: leaderboard

ChartAnno (2026) asks multimodal LLMs to add annotations to the executable code of real-world charts from instructions at three levels of specificity. A GPT-5.4 judge rates visual clarity, organization and attention guidance from 1 to 5 (0 for failed output); higher is better. Chart code is the only input, and implementation-level instructions specify the annotation elements and styling.

Metric: Design effectiveness (out of 5): mean of visual clarity, annotation organization quality and attention guidance, each an integer rubric score from 1 to 5 given by a GPT-5.4 judge, 0 for failed or missing output; annotated chart code generated from the unannotated code of 1,200 real-world charts; chart code input only; implementation-level instructions that specify the annotation elements and their visual properties.
