A sunburst chart is a data visualization technique that displays hierarchical data using concentric circles. Each ring represents one level of the tree hierarchy, with the root at the center. Arc segments within each ring encode values proportionally by angle, and parent-child relationships are shown by containment. Persistence mechanism: rendered as SVG or canvas graphic by charting libraries. [formal: solis radiatus | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.96]

TESTED INSTANCE_OF: A sunburst chart IS a specific kind of plot — it displays hierarchical data using concentric circles divided into segments, with each level of hierarchy as a ring. A competent speaker would call it 'a plot'.

The sunburst chart's encoding requires hierarchical data — concentric rings map to hierarchy depth. Remove hierarchy as a concept and the chart's radial segmentation has no referent; the encoding collapses. Present-tense constitutive dependency per Law 8.
