A sunburst diagram is a hierarchical data visualization that encodes nested categories as concentric rings, where each ring represents a depth level and the angular span of a segment indicates its proportion within its parent category. Parameters: (1) a tree-structured hierarchy with parent-child relationships, (2) concentric rings encoding depth levels, (3) angular encoding for within-category proportions. Persists through SVG/CSS rendering of nested arc segments with hierarchical color mapping. [formal: solisradium | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.02]

Definition
Why it is in scope
A human-made data visualization that represents hierarchical data as concentric rings, where each ring level is a hierarchy depth and segments within rings show sibling categories proportionally by their values

A sunburst diagram is a specific kind of tree diagram — it displays hierarchical data as concentric rings where each ring represents a level in the hierarchy. Files against nearest kind, not chart.

A sunburst diagram is a specific kind of plot that displays hierarchical data using concentric rings where each ring level is a hierarchy node, and segment angles represent values. It IS a plot: a structured visual encoding of data. The nearest kind is plot (not chart — charts are a broader category and plot is the immediate parent class of visualizations like this).
