A reactive, battery-included Python notebook that solves the 'hidden state' mess of Jupyter
Marimo is the niche answer to the chaos of Jupyter Notebooks. In traditional notebooks, you can run cells out of order, leading to "hidden states" and broken code. Marimo is reactive: if you change a variable in one cell, every dependent cell updates instantly, just like a spreadsheet.
### Why Data Scientists are Switching
1. **Deterministic Execution**: No more "did I run cell #4 before cell #12?" The state is always predictable.
2. **Built-in UI Elements**: Add sliders, buttons, and input fields that directly influence your code without writing complex HTML/JS.
3. **Pure Python**: Every notebook is stored as a standard `.py` file, making it version-control friendly (no more messy JSON diffs in Git).

**Best for**: Researchers and engineers who want a more stable, reproducible environment for exploratory data analysis and internal tooling.
