The underlying library seems pretty stable, but tricky to customize. The hardest part was undoing their script dependency loading. It would be nice to use the resource dependency scheme you implemented.

If I were to re-implement this today, I think I would still use the same library for the main timeline. However, I probably would have integrated with the new LabKey charting package for the line charts (which wasn't an option at the time).

Let me know if you find a different package that does the same thing.
