<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

- **Documentation**
- Updated the Jupyter Notebook to improve the clarity of the JSON
structure by renaming keys and adding new entries for better
organization of repeatable items.
- **Enhancements**
- Improved flexibility of the `ArgumentData` class to handle various
data structures more effectively.
- Refined error handling in the `print_html` method for better
robustness against unknown data types.
