In this article, we will be providing a brief on Sunburst Chart. Sunburst chart is basically a stacked pie chart. It is created by stacking necessary amount of pie charts on top of each other. This is ideal for presenting the hierarchical data. Each level of the hierarchy is represented by one ring or circle with the innermost circle. A pie chart can only represent a single dimension data, whereas a circle packing can represent many dimensions data.
This is unique in presenting the hierarchical data. Each level of the hierarchy is represented by one ring or circle with the innermost circle as the top of the hierarchy. A sunburst chart without any hierarchical data looks similar to a donut chart.
However, a sunburst chart with multiple levels of categories shows how the outer rings relate to the inner rings. The sunburst chart is most effective at showing how one ring is broken into its contributing pieces, while another type of hierarchical chart, the treemap chart, is ideal for comparing relative sizes.
