Highlighting intervals tutorial

[jordanplanders]

Build a tutorial showing how to highlight intervals:

• overlay
• above
• below

with labels:

• added to the legend (e.g. if there are categories of labels)
• per interval with pointers

Bonus:

• labelling specific points on a figure
• making an event timeline?

Fodder: geologic timescale (Cenozoic), MIS
