Pulls in a curated collection of D3.js examples from jiannanya's snow-d3 repository to teach Claude how to build interactive visualizations. You get reference implementations for common chart types like bar, line, treemap, force graphs, Sankey diagrams, and choropleths, plus techniques for animations and scroll-driven interactions. The skill works in prototype mode, so it's best for editorial work, dashboards, and data-rich mockups where you need something more sophisticated than a basic charting library. If you're already comfortable with D3 conventions, this gives Claude enough context to generate working code without you having to explain force simulations or hierarchy layouts from scratch.
