Try a Donut chart. This will give you the rings, and you can make 20
segments in each ring to build up the wedges.

How do I create a chart that looks like a dartboard, i.e. it works like a
radar chart, but is round and with the ability to colour different "rings"
to
represent different bands of scores?
