I’ve added another video to my YouTube channel demonstrating how to make the above graph in my web app for graphing data, Playfair. Find out more about Playfair at the github page. I’ve made a simple tutorial that walks you through a couple Playfair graphs. And you can try Playfair online here (Chrome only right now).
The third graph on this elections forecast page at fivethirtyeight.com caught my eye because there are a few different graphical elements on this chart so re-making it is a good way to show off Playfair’s ggplot2-like capabilities. The whole thing took about 26 minutes and I got pretty darn close to the original. Check out the full process in the video below:
