@electricarchaeo W/o meaning to seem like a stalker... GitHub repo updated to reflect that I can: loop through a selection of amphitheaters in order to make an embedded popup for each that indicates its size in relation to all known sizes.

Folium interactions a little wonky. You sometimes have to click twice. Might depend on window size?
