Reference

Blueprint Chart's reference material covers the same model from two angles:

• BPC DSL — the .bpc text format. Source-level grammar, properties, annotations, scenes, transforms.
• API — the TypeScript surface of @blueprint-chart/lib. Every exported symbol — types, enums, helpers, rendering primitives, the chart-type registry, and the DSL parse/serialize bridge.

The two views are bridged by parse / serialize (.bpc text ⇆ AST) and by the ChartType enum (the list of valid chart-type identifiers is exported from the lib).

When to read which

• Authoring .bpc files (by hand or in the editor): start with the DSL overview.
• Embedding Blueprint Chart in a TS/JS project, consuming the AST, or building custom renderers: start with the API reference.
• Both: read in either order — they share examples (the bitcoin-price sample appears in both).
