Microsoft Research releases Flint, a visualization language for the AI era

The Neuron · 3 days ago

Microsoft Research released Flint, an open-source visualization language that lets AI agents generate polished charts from simple, human-editable specifications. In evaluation across three AI models on Tidy Tuesdays test data, Flint achieved judge scores of 16.27 with GPT-5.1 compared to 15.91 for a baseline direct Vega-Lite approach. The same Flint specification can compile to multiple visualization backends including Vega-Lite, Apache ECharts, and Chart.js, with an accompanying MCP server enabling agents to create and render charts directly in chat environments.
