# ChartAct Preview

This repository is a preview release of ChartAct, an interactive benchmark for dynamic chart understanding. The full benchmark will be released after formal publication.

Paper: [ChartAct: A Benchmark for Dynamic Chart Understanding](https://arxiv.org/abs/2605.26994)

GitHub: https://github.com/wulin-wulin/OSWorld_Chart

## Contents

- `data/dynamic_chart_preview.jsonl`: 5 Dynamic Chart preview samples.
- `data/dashboard_chart_preview.jsonl`: 5 Dashboard Chart preview samples.
- `evaluation_examples/`: minimal OSWorld-style task configs for the preview samples.
- `web/` and `web_insert/`: chart webpages required by the preview samples.
- `label/` and `question_answer/`: metadata and QA annotations for the preview samples.

This preview is intended to show the benchmark format and runnable framework without releasing the full evaluation set before publication.
