summary
A reactive Python notebook called Mimo enforces single definitions so a reassigned X throws an error instead of leaking state, and it builds a directed acyclic graph of cell dependencies so children update automatically when parents change. It auto-detects and auto-install missing packages, exposes UI widgets (slider, dropdown) that drive live charts, supports columnar SQL with DuckDB + Polars integration, lets chart selections return images/rows, and can run as a shareable app or CLI.
