Zero spacing option for pie chart

### Feature Proposal

Currently 0 spacing is a default which results in non-zero spacing. It is not possible to specify 0 spacing, i.e. 0 pixel space between arcs on a pie chart. In our scenario having too many sections makes the last few sections appear entirely in white because of the non-zero spacing. Some sections before that appear partially in white, as if some fog effect was applied.

The effect looks like this:
