Really liked this notebook! Great dataset chosen for the topic at hand; each cell block walks through and conveys a story (imo); the comments are really descriptive and I enjoyed that. Thanks a lot for the contribution ❤️

Will see if there are any other things that I missed out on (a little late here, will look into this tomorrow).

@etrotta Hope you had a chance to go over the above review comments; can totally understand if you've been busy (work/otherwise). Let me know if you need any help w/ this notebook/PR.

@Haleshot I moved the imports a while ago, but I am not sure what else was missing besides that?

I was waiting for suggestions regarding the balance I mentioned in the other comment before splitting anything as for me the way it stands today is good enough, but more importantly I assumed you'd add more comments after

Will see if there are any other things that I missed out on (a little late here, will look into this tomorrow)

Looks like there are some typos (failing CIs).
