marimo: You can edit a notebook in Marimo by running:
marimo edit marimo-demo.py
However, you may also choose to run it as a web application. This is done by running:
marimo run marimo-demo.py
This will render the outputs of the cells as a web application. You may choose to run it in the linear layout, but it is also possible to run it in a grid layout. This is basically like having a canvas where you can click and drag cells around.
