SKILL.md

This skill helps you create custom, interactive data visualizations using D3.js (Data-Driven Documents). D3 provides low-level building blocks for data-driven DOM manipulation, visual encoding, layout algorithms, and interactions—enabling bespoke visualizations that chart libraries can't provide.

Data Joins: Bind arrays to DOM elements, creating one-to-one correspondence Scales: Transform data values → visual values (pixels, colors, sizes) Shapes: Generate SVG paths for lines, areas, arcs from data Layouts: Calculate positions for complex visualizations (networks, trees, maps) Transitions: Animate smooth changes between states

Use when: Building bar, line, or scatter charts from scratch

Use when creating custom, interactive data visualizations with D3.js—building bar/line/scatter charts from scratch, creating network diagrams or geographic maps, binding changing data to visual elements, adding zoom/pan/brush interactions, animating chart transitions, or when chart libraries (Highcharts, Chart.js) don't support your specific visualization design and you need low-level control over data-driven DOM manipulation, scales, shapes, and layouts.
