Can I use SQL directly in marimo?

Yes, marimo has built-in support for SQL using DuckDB. You can query DataFrames or external files and the results are automatically integrated into the reactive notebook environment.

What makes marimo notebooks different from Jupyter?

Unlike Jupyter, marimo is reactive; when you update a variable in one cell, all dependent cells automatically re-run. This eliminates the 'hidden state' problem and ensures reproducibility.

How does this skill handle UI elements?

The skill provides patterns for mo.ui components like sliders, dropdowns, and forms. It follows best practices such as separating UI definitions from their .value access to maintain reactivity.

Does this skill support common Python visualization libraries?

Yes, it includes optimized patterns for Matplotlib, Plotly, and Altair, ensuring that charts are returned as the final expression in a cell for proper display.
