Chart Compiler Gallery
ChartSpec data compiles into resolved scales, layer specs, glyph definitions, scene graph nodes, and a single SVG renderer.
Sunburst Diagram
Hierarchy rows are normalized and partitioned into annular sectors with generated SVG path data.

Build Path
This example is rebuilt from gallery data source hierarchy-rows by recipe sunburstDiagram: raw table rows -> TabularSource -> pipeline drafts -> analyzeAuthoringDrafts() -> materialized ChartSpec -> compileChart() -> SceneGraph -> SVG. The graph below shows the authored pipeline stage.
