Per a Microsoft Research blog post published July 8, 2026, Microsoft Research and the project site introduce **Flint**, an open-source visualization intermediate language that lets AI agents generate polished charts from compact specs. The project includes the `flint-chart` library and a `flint-chart-mcp` server, according to the project documentation. The project site states Flint supports **46 chart types** and can compile a single spec to **Vega-Lite**, **Apache ECharts**, or **Chart.js**. The GitHub repository notes the project exposes **70+ semantic types** and lists **354** stars on the repo.
