I stumbled upon this excellent example of a Jupyter notebook.


That page is a Jupyter notebook that the author self-published. If you look
through the comments, someone found the link to the actual Jupyter notebook
as well.

It's clearly a very powerful presentation media that is open source and
very versatile. And as this example shows, even if you have a web service
running, you can self publish Jupyter notebooks. I think the key issue is
that it would take much more work to publish that page without using the
Jupyter notebook media. And so it's worth becoming familiar with it.

I've read through other Jupyter notebooks, and the media is very versatile
in the information content one can publish.
