This example demonstrates the effects of different 3D angles.
ChartDirector allows the 3D depth and angles to be configured using
PieChart.set3D and
PieChart.set3D2.
This example also demonstrates how to disable sector labels. This is setting their colors to
Transparent using
PieChart.setLabelStyle.
