# claud3 > Catalogue stub — full package: [dtran320/claud3](https://github.com/dtran320/claud3) ## Decision tree 1. **Is the package already installed?** Check: `~/.design-agent-skills/skills/claud3/SKILL.md` exists. - Yes → invoke `claud3` and proceed - No → go to step 2 2. **Do you have shell access?** - Yes → run the install command below, then invoke the skill - No → show the install command; in Claude Code, send it as a chat message starting with `!` — add `-g` for global install or omit for project-only ## Install command ```bash npx skills add dtran320/claud3 ``` ## Invoke after install - Skill name: `claud3` - Trigger phrases: "claud3", "D3 Tufte", "80 chart types", "D3 dark theme" ## What it does Applies Edward Tufte's data visualization principles to D3.js chart generation. Analyzes the underlying data question to select the most appropriate chart type from a library of 80+ options, then produces self-contained single-file HTML using D3 v7 with a dark theme, responsive layout, direct data labels (no separate legend), and contextual annotations. Includes a playground mode for interactive exploration and refinement. ## When NOT to use - Multi-library visualization agents — use data-viz-agent instead - AntV/G2 charts — use antvis-chart-skills instead - Quick single charts without Tufte constraints — use d3js-skill instead
