Build Path

Gallery Nightingale Rose Pipeline

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