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 visualizes COVID-19 cases and deaths worldwide, based on data from Our World in Data as of November 24, 2020. Regions nest into countries, revealing the global distribution at a glance. Custom HTML labels show formatted case counts, while tooltips display both total cases and total deaths at every level.
