RadarChart labels away from graph

I cannot find a way to move labels closer to the graph. They are far away for some reason.
Also, I cannot draw circles at angles, below label. Is that possible?

No file, test, or entry point is identified. Start by reproducing the RadarChart shown in the issue, then inspect how label spacing and angle-based circle drawing are currently handled; done means the desired label placement and circle behavior are clearly defined and verified.
