Parliament charts are used to show the party composition of a government, usually wheeled out for election results.

Inspired by Flourish's component, I wanted to have a go at the geometry involved in building this. I had hoped for a perfect solution where all of the positions are determined in one go with even spacing, but I had to settle for an iterative approach with rounds of balancing out the number of dots in the rings, which is where those jagged divisions between the sections come from.
