3D Donut Chart
Making pie chart 3D
A 3D pie chart is like regular pie chart. They’re identical in configuration, except that the former uses
PieChart3D class to instantiate the chart, and
PieSeries3D for its series.
It also introduces additional settings
angle to configure depth (height) and angle at which we are viewing the chart.
Configurable inner radius
To make a donut chart out of a regular pie chart, we simply need to set
innerRadius property of the chart.
It can either take relative percent value, or fixed pixel radius.
