Nested Pie Chart

The Nested Pie Chart is a special type of chart that allows you to show symmetrical and asymmetrical tree structures in a consolidated pie-like structure. The chart is visualized as a series of concentric circles arranged like a pie. The circles are divided into segments that represent each of the data values; the ratio of each segment is determined by the corresponding data value. This chart can be used to show organizational structures, interlinked tree data (like friends of friends), category-wise sales break up, and so on.
You can find a more in depth explanation about the nested pie on this page: https://echarts.apache.org/examples/en/editor.html?c=pie-nest
