About

A ring chart, also known as a sunburst chart or a multilevel pie chart, is used to visualize hierarchical trees, depicted by concentric circles.

The circle in the centre represents the root node, with the hierarchy moving outward from the center. A segment of the inner circle bears a hierarchical relationship to those segments of the outer circle which lie within the angular sweep of the parent segment.
