I have an ongoing project to make posts for mental_floss articles I wrote way back when that I do not have an archive for. Here's another one, from 2014.
Can graphs be funny? That’s a silly question, as you’ve seen plenty of funny flowcharts, pie charts, and Venn diagrams, as well as other charts and graphs, made just for fun here already. But there are other kinds of charts that have a joke in them somewhere. Doghouse Diaries explains a graph's potential for humor. This type of chart is called an XY Plot, or scatter chart, which places items along two axes depending on the two variables measured in relationship to other items. See all of them in a post I did for mental_floss.
