US Medical Insurance costs - Review appreciated

Hello, I came here to share my project on this project for the data scientist career path. It was fun to do, I opted to use pandas and matplotlib, altough I am only starting to get a grasp of these modules. I also opted to code in a IDE and use the terminal, for that, I created a module that makes it easier for any user to use the program in the CLI. It was hard because of my knowlege of pandas and matplotlib is still very low. Here is the link: US Medical Insurance Costs

I appreciate any feedback, I know there is a lot I can improve.
