Today is the birthday of John Venn (of Venn diagrams fame). He was born on this day, 4th August 1834. So I was thinking about diagrams today and finally got around to looking up code for the trendiest-plots-of-2017, 'Joy plots'. As of July 2017 we now have ggjoy plotting code in R (https://github.com/clauswilke/ggjoy) and they're also beautiful in Python's Seaborn (https://github.com/mwaskom/seaborn/pull/1238).
They're named after the Joy Division album cover. But finding out what 'Joy Division' actually means (https://en.wikipedia.org/wiki/House_of_Dolls) is always going to make me less joyful about the joy in using them.
