Create sunburst charts online for free. Display hierarchical (nested) data using concentric rings — ideal for organizational structures, file systems, and multi-level category breakdowns.
What Is a Sunburst chart?
A sunburst chart uses concentric rings to represent hierarchical data. The innermost ring represents the root, and each subsequent ring represents a deeper level of the hierarchy. Clicking on a segment drills down into its children. Sunburst charts are used for organizational charts, file system visualization, taxonomy displays, and any multi-level categorical data.
