希望未来可以支持3d饼图

### What problem does this feature solve?

未来有计划支持3d饼图吗，3d环形图

### What does the proposed API look like?

目前只能用3d曲面来替代，但是效果一般，没有标签，没有指示线

No files or tests are named. Start by reviewing the existing 3D surface-chart support and how chart APIs handle labels and guide lines; define the proposed 3D pie and donut behavior before implementation. Done should include usable 3D pie and donut charts with labels and guide lines.
