Portfolio Project: U.S. Medical Insurance Costs

Check out my first Data Science Portfolio Project on GitHub:

Portfolio-Project-U.S.-Medical-Insurance-Costs

Hi there,
I recently finished my first Data Science Portfolio Project.
I suppose what I did looks a bit bumpy, but I tried to work on the project using only the instruments given so far, after finishing python fundamentals.
Any comments, corrections, additions or jokes will be highly appreciated.
Thanks to all
