A ggplot-based Marimekko/Mosaic plot

November 1, 2017 | That’s so Random

One of my first baby steps into the open source world, was when I answered this SO question over four years ago. Recently I revisited the post and saw that Z.Lin did a very nice and more modern implementation, using dplyr and facetting in ggplot2. I decided to merge ...
