Flint is a visualization intermediate language and TypeScript library that compiles compact, human-editable chart specs into Vega-Lite, ECharts, Chart.js, Plotly, or Excel-native charts. It also ships an MCP server so AI agents can create, validate, and render polished charts with themes like NYT, Economist, Swiss, and McKinsey.

Use cases

• have an AI agent generate good-looking charts from a simple spec
• compile a semantic chart spec to Vega-Lite or ECharts
• add chart creation tools to an MCP client like Claude or GitHub Copilot
• render charts in publication themes like Economist or McKinsey
• export editable Excel charts from data
• validate and render charts from a chat or coding environment

When to choose

• you want AI agents to produce expressive charts without hardcoding verbose layout parameters
• you need one compact spec that targets multiple charting backends
• you want themed, publication-quality visualizations
• you want to expose chart rendering to agents via MCP

When to avoid

• you need direct low-level control over every charting parameter
• you are not using JavaScript/TypeScript or an MCP-capable agent
• you need chart types outside what the supported backends offer
