I started drafting a blog post that really needed a visual aid. So I followed the advice of my high school stats teacher: when you don’t understand a problem, draw a picture.
I pulled up the art app on my tablet and drew this:
It seemed like a reasonable four circle venn diagram. Except when I started labeling it, I realized I needed the pink and the blue to overlap with just each other and not grey or yellow.
So I redrew it.
And then I figured the jetlag was setting in because no matter how I drew it, I couldn’t make the circles overlap right.
So I decided to just google four circle venn diagram and steal someone else’s pretty graph off the internet and re-purpose it.
Except when I googled it, I found out that you can’t make a four part venn diagram with circles!!
Apparently this is because circles can only intersect in at most two points. But you can make venn diagrams for sets N>3 with other shapes like ellipses.
Mind. Blown.
