Semiotic

About Semiotic

Semiotic is a React data visualisation library designed for AI-assisted development and streaming data, from simple line and bar charts to network graphs and coordinated views. Its MCP server lets Claude select, validate, repair, render and inspect charts, with structured schemas and diagnostics so the chart configuration is checked rather than guessed. Example requests: "Build a bar chart of signups by month with Semiotic", "This chart renders empty: diagnose and fix the configuration", "Turn this dataset into a network graph of who works with whom". Semiotic requires React 18.1 or later and is published by nteract.
