Hey breyenguyen, really nice submission: I really like the high level approach you to took to finding the distributions to start off with and the detail you broke it down to.
One small suggestion with your code, when plotting a bunch of different metrics as subplots (or anything repetitious like really), that’s probably a good opportunity to make a loop of some sort (you can check out what I did in my code below, from my own submission for the project which you’re welcome to review for me btw!)
One another thing worth considering is the degree to which an increase in GDP impacted life expectancy (or vise versa). Does a 4x increase in GDP = a 4x increase in life expectancy? Does it depend on the country? What can that say about the causality between those two metrics, and are there other variables at play?
Cheers,
Tolly
