Comments¶

1. DataFrame.hvplot (via the Python package hvplot) is the most convenient way to use HoloViews.

2. If you want to use HoloViews directly, it is better to create a HoloViews.Dataset object and use it for visualization.

3. The groupby option generates a plot with a dropdown list for interactively showing plots of different groups. You can overlay plots of different groups together on the same plot simplify by calling the .overlay()
