This gives Claude comprehensive guidance on building custom data visualizations with d3.js, from basic bar charts to complex network diagrams. The documentation covers two integration patterns: direct DOM manipulation for full d3 capabilities, and declarative rendering for framework compatibility. You get practical code for responsive sizing, proper margin conventions, and common chart types with working examples. The skill is honest about when to skip d3 (use Three.js for 3D instead), and the structure section alone will save you from reinventing the wheel on every project. If you're building anything beyond standard chart library offerings or need fine-grained control over transitions and interactions, this is solid reference material.
