Pie / Donut
A pie / donut chart displays pie slices with sizes proportional to the values they represent.
Donut charts act just like pie charts, except for an adjustable donut hole in the center of the chart. Refer to Donut Chart for more information.
Pie / donut charts support several customization options, such as labels, legends, multiple series and more. Refer to Pie Chart Features for details on how to use these features.
