Could you please provide some example on using "Data Understanding Tool"?

Thanks for updating the paper.

In the updated paper, you mentioned you have implemented a "data understanding tool" based on world model. This is super useful and important.

Could you provide some example on how to use the tool?

The issue names only the “data understanding tool” and the updated paper; no source file, test, or entry point is identified. First locate the tool and determine its current interface, then document a concrete usage example. Done means the repository includes an example that explains how to use the tool.
