d3-animated-data-visualization
Production guidance for converting sourced data and approved claims into truthful, accessible, deterministic animated visualizations with D3. Use for data-driven charts, maps, networks, hierarchies, transitions, annotations, responsive video variants, frame-by-frame browser rendering, and visualization QA; not for generic dashboards, unsourced decorative charts, or ordinary motion graphics without a data contract.

# D3 animated data visualization
Use this skill when data determines the marks, scales, layout, labels, and animation of a rendered-media sequence. D3 is useful when standard chart components cannot express the required encoding or choreography with sufficient control.
The job is not to make numbers move. The job is to preserve meaning while controlling attention over time. Source integrity, denominator, units, uncertainty, scale, and transformations are production inputs, not footer decoration.
## Evidence stance
- **Documented fact:** behavior or requirement from official D3, W3C, or cited standards documentation.
- **Production heuristic:** a practical choice that depends on the dataset, audience, and delivery.
- **Empirical observation:** a measured result from the actual data, layout, rendered frames, or encoded output.
D3 packages and APIs are versioned independently. Facts were checked **2026-07-12**. Record exact module versions and re-check official documentation when the installed set differs.
