Chart Compiler Gallery
ChartSpec data compiles into resolved scales, layer specs, glyph definitions, scene graph nodes, and a single SVG renderer.
Symbol Map
Rebuilds the symbol map with manual lon/lat domains, size and color scales, grid guides, points, and labels.

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