Chart Compiler Gallery
ChartSpec data compiles into resolved scales, layer specs, glyph definitions, scene graph nodes, and a single SVG renderer.

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