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 displays European population data organized by region and country. A custom four-color palette with progressive darkening distinguishes each hierarchy level, while scale-formatted labels and tooltips display population values in millions for easy reading. The parent-independent calculation method sizes each segment based on its own value.
