There are some docstrings that are not consistently formatted and sometimes result in a supposedly unexpected format in the ipython.readthedocs.io

An example:

Hello,

Make image tags consistent

The images will be tagged as described below

• base-notebook:
  • SHA: Commit short SHA
  • python-$VER: Python version
  • notebook-$VER: Jupyter Notebook version
  • lab-$VER: JupyterLab version
  • hub-$VER: JupyterHub version
• minimal-notebook:
  • all upstream tags
• scipy-notebook:
  • all upstream tags
• `r-no

The plotting UI leaves a lot to be desired:

• When you bring up the plotting UI, it's not obvious that you have to do some work to make a plot happen. If you don't, there's no error message, just a never-ending wait. (see https://gitter.im/polynote/polynote?at=5e0e36f9eac8d1511e9ed2ff )
• Why do we make you drag things onto axes? Especially when there is only one axis it could go onto (at leas

Use case

Polyaxon tracking can be used to automatically log all information generated by Ludwig.

We should probably think about adding support for Polyaxon's tracking module in Ludwig contrib.

Besides being a great interactive programming environment, Pluto is also a carefully engineered.... web server? That's right! To make Pluto work, we spent a lot of time into making a static asset server + websocket server. They are actually pretty good! We might want to split it into its own package one day.

As part of making Pluto a good web server (which benefits the project in numerous ways)
