Microsoft Research releases Flint-Interactive for AI-authored interactive charts

Microsoft Research published Flint-Interactive, an extension of its open-source Flint visualization language that lets AI agents and developers specify interactive chart behaviors by describing what a user interaction means in data terms. The release comes three months after Flint's initial debut in July 2026.

• Flint-Interactive adds a semantic layer between the browser and developer code
• Built-in presets cover cross-filtering, tooltips, brushing and synchronized zoom
• Flint's semantic type system includes more than 70 built-in types
• Three update operators: set style, set annotation and set viewport
