marimo

sublimated renders marimo .py notebooks with syntax highlighting, dependency visualization, and execution support.

• cells are Python functions decorated with @app.cell — explicit inputs/outputs form a DAG
• markdown cells use mo.md() and render as rich text
• dependency arrows show data flow between cells
• mo.ui.* widgets detected and previewed (slider, dropdown, text, checkbox)
• execute notebooks via the run button — outputs render inline under each cell
• run history tracks every execution with timestamps and duration
• compare outputs between runs side by side
