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 employee headcount by country and region. The ordinal-from-leaves calculation method sizes each segment from the outermost level inward, giving individual countries proportional weight. A custom tooltip sums children values for each parent, while a four-color palette with progressive darkening creates a clear color gradient from ring to ring.
