there's a specific type of pie chart that's good: a "clock chart".

this is when you're depicting how long some contiguous sequence of events took as a fraction of a whole duration. you map the start and end to the 12 o'clock position, and the intervening ones wrap around clockwise.

e.g. the history of the universe with the big bang at the top, then formation of stars, galaxies, planet earth, dinoaurs etc as you go around clockwise. then human history is a tiny slice at like 30 seconds to midnight or whatever it is.

this works because it piggybacks on people's existing strong spatio-temporal intuition for clock faces. time is a flat circle.

I'll concede that this is a reasonable case.
