Request for Code Review: U.S. Medical Insurance Costs Analysis

I completed this project as part of the career path Data Scientist: Analytics Specialist. Since this is my first project, I would like to ask for a more general review, even if this is discouraged under the general guidelines on asking for a code review.

If someone is versed in visualization libraries like Matplotlib (or any similar library), I would appreciate advice on how to generate the last plot in the notebook, which I couldn’t manage to do in code. I resorted to manual creation in Adobe Illustrator.

In general, it was a very time-intensive project for me. Not being able to use Pandas and similar tools (yet) made it necessary “go the long way” in some parts of the notebook. The main barrier for me was my distinct lack of statistical and data-analytical knowledge, which hopefully will increase over the course of the career path.
