What's Good

MIT (microsoft/data-formulator). Free local install via `uvx`/`pip` (PyPI `data_formulator`) plus online demo at data-formulator.ai. Interactive AI-powered explore→visualize loop aimed at analysts who want agent-shaped chart iteration without a full BI suite. ★17,455 on GitHub 2026-09-28.

The Catch

Vs marimo: marimo is a reactive Python notebook runtime; Data Formulator is a dedicated AI viz/exploration app. Vs Pandas/Polars notebooks alone: you still bring model API keys for the agent path, and complex ETL still belongs in code. Microsoft research-to-product surface — expect UX churn; not a replacement for production BI (Metabase/Looker).

Verdict

MIT Microsoft AI data-viz when you want agent-shaped chart exploration — not marimo notebooks, not a BI warehouse product.
