microsoft/flint-chart

Flint is a visualization language that turns compact, human-editable chart descriptions into charts without requiring an agent to specify every layout detail. Its library produces output for formats including Vega-Lite, ECharts, Chart.js, Plotly, and editable Excel charts, while its MCP server lets agents create, validate, and render visualizations. The catalogue skills, agent, and MCP integration help coding agents use Flint.
