Feature Request - Dual Layer Data Representation on Timeline

[SchneiderSam]

I would like to suggest the implementation of a feature that allows the representation of data both above and below the timeline, similar to the examples provided. This feature could offer users more flexibility in showcasing various types of data, simultaneously. For instance, people could be represented below the timeline while events are depicted above it. This bifocal approach might enhance readability and user engagement.
