Visualization Documentation

[nreinicke]

We should create some documentation for how to use the visualization functions/script (Something like the batch-trainer README.md). It should detail the following:

• How to setup the visualization config file for running the visualization script (detail what each parameter is, which ones are required, show some examples of a config file)
• How to use the visualization function in a notebook or script. There is already some documentation for the function in docstrings, but perhaps we could add an example of how to use it in a notebook
