A Sunburst chart is a chart that represents hierarchical data, each level of the hierarchy is represented by one ring or circle with the innermost circle as the top of the hierarchy. Sunburst charts with one level of categories will look similar to a doughnut chart, while Sunburst chart with multiple levels of categories shows how the outer rings relate to the inner rings. The Sunburst chart displays each group with color and the sub-categories by division.
