### Steps to Reproduce

Check the above demo, and hover on "c", you can see that it's overlapped with "d".

### Current Behavior

Sectors may overlap when setting `minAngle`.

### Expected Behavior

Sector angles should be adjusted when some sectors are smaller than `minAngle`. The currect implementation only set angle to be `minAngle` when it's smaller but not adjust other sectors' angle. But since `minAngle`'s document is missing, probably no one is using this option unless have read the source code.
