Donut chart API reference

Summary: The Donut chart is now a variant of the Pie. It may be preferable to using a Pie and multiple Donuts can be nested.

The Donut chart was formerly a separate type; however it's now simply a variant of the Pie chart. In the example code the variant property is highlighted and this is the property to use in order to get your Pie chart to appear as a Donut chart.
