Created attachment 138375 [details] Charts start from the bottom Circular charts seem to begin from the 6 o'clock position and proceed in a clockwise direction. This feels unusual; typically these kinds of charts begin from the 12 o'clock position and proceed in a clockwise position, to mimic a clock itself. By starting at the 6 o'clock position instead of 12, these charts are kind of half imitating a clock and it feels odd to me.
TBH I am not sure the clock metaphor hold here. Gauges on machines or other equipment often start somewhere on the bottom left. Another example is a speedometer where depending on the car 0 is anywhere ranging from 6 o'clock to 9 o'clock.
A speedometer gauge usually has a very particular appearance and starts around the 7 o'clock position, with a big empty area between 7 and 9. We don't do that, so I don't think emulating a speedometer was the goal or makes sense. If we do want to move towards looking more like that explicitly, I would actually be fine with it, but if we don't, then I don't think going there anyway but only halfway is the best approach. :)
