The dashboards layout extension is an add-on for Jupyter Notebook. It lets you arrange your notebook outputs (text, plots, widgets, ...) in grid- or report-like layouts. It saves information about your layouts in your notebook document. Other people with the extension can open your notebook and view your layouts.
For a sample of what's possible with the dashboard layout extension, have a look at the demo dashboard-notebooks in this repository.
Detailed installation instructions appear in the Getting started page of the project docs. Here's a quickstart using pip or conda:
# install using pip from pypi and then activate the extension
pip install jupyter_dashboards
jupyter dashboards quick-setup --sys-prefix
# install using conda from conda-forge, no activation required
conda install jupyter_dashboards -c conda-forge
The Development page includes information about setting up a dev environment and typical dev tasks.
