Jupyter notebook for visualize.py

[Miguel Xochicale, PhD]

HI @jcl5m1

I see that you are already have ventilator_data_analysis.ipynb But perhaps, to keep track of changes in the same repository of visualize.py, a Jupyter notebook might be helpful. Will later put a PR for that :-)

Agreed would be helpful to track code changes, if you PR a working notebook I can merge it
