Chart Compiler Gallery
ChartSpec data compiles into resolved scales, layer specs, glyph definitions, scene graph nodes, and a single SVG renderer.
Calendar
Rebuilds the calendar chart with month-cell layout rows, day numbers, weekday labels, and a color legend.

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