Making a Chart in grasshopper

Im trying to make a custom chart in grasshopper, can anyone help me make the pink arc parametrically (attached below)

i was able to make the circle chart in grasshopper but im not sure how to fill the chart graphically with the data i need.

the pink arc is an example i would need to extend or shorten the arc anywhere on the chart.


Please post minimal geometry and gh file if possible, people are more likely to help if they don’t have to recreate the objective.
