A compact spec compiles to native Vega-Lite, ECharts, Chart.js, Plotly spe…

This repo contains two main components:

`flint-chart`: a JavaScript/TypeScript library that compiles the same Flint input into Vega-Lite, ECharts, Chart.js, Plotly, or Excel-native output. `flint-chart-mcp`: an MCP server that lets agents create, validate, and render charts directly from a chat or coding environment.
