Brings React data visualization directly into Claude with 43 chart types spanning standard plots, network graphs, streaming data, and geographic maps. The MCP server exposes validation, diagnostic, and suggestion tools backed by machine-readable schemas, so you can ask Claude to generate visualizations and catch prop errors before rendering. Includes `diagnoseConfig` for anti-pattern detection and typo suggestions across the entire Semiotic API. Particularly useful when you need coordinated dashboards or realtime charts alongside static plots, since it handles force-directed graphs, Sankey diagrams, and streaming canvas rendering that most libraries skip. The `semiotic/ai` import provides HOC charts optimized for LLM code generation with built-in error boundaries.
