A sunburst chart is an interactive multilevel ring visualization that represents hierarchical data as concentric arcs, where each ring corresponds to a level in the hierarchy and the angular size of each segment reflects its value.
This sample shows how gold medals at the 2014 Sochi Winter Olympics were distributed across countries and sports. Click any country segment to drill down into its sport-level breakdown. A dynamic center label displays medal counts for the selected segment, and the outermost ring toggles visibility during drilldown to keep the view focused.
Follow the step-by-step Sunburst Chart Tutorial to learn how such charts are built. See the Sunburst Chart documentation for all configuration options, or explore this chart type in Chartopedia.
