Visx Foundation

Use when porting or reimplementing visualization primitives from visx (@visx/*) — scale operator pipeline, chart keyboard-nav state machine + ARIA tree, brush extent FSM, zoom matrices, responsive/text/spring primitives: d3-scale config application with correct operator ordering, keyboard-navigable + screen-reader-accessible charts, pixel-to-domain brush selection with ordinal support, cursor-anchored zoom transforms, parent-size responsiveness without layout loops, SVG text measurement/wrapping, animated line enter/exit trajectories, and referentially-stable data/accessor plumbing.

visx: Chart Primitive Kernel Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: visx; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: master@485c0359664ee8e612992defb16e1f035ed40b23.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Scale plane; A11y plane; Brush plane; Interaction plane; Responsive plane; Text plane; Spring plane; Kernel plane.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
