Three projects down! Two to go. As always, good job and here are a few comments for that extra 110%.
Visuals
You used the data well to reason through your decisions.
You managed to write concise text while also describing all that you need. Very nice!
Nice visual representation!
Code
I didn't see any functions :( You can replace long for loops, but especially for the third notebook, visualization, you can turn all that repetitive code into a function! It will save you a lot of time, even if it seems like more work upfront.
You want at least 5 cleaning functions that perform different tasks.
Having to import 'warnings' is often a sign of needing to update your code. You can google any lines you aren't sure of!
Organization
Great folder organization, as always.
Well done committing often and adding accurate descriptions to each commit.
