"While working on the ZIPScribble map, I started to wonder how to untangle the beautifully scribbly lines, and finding the shortest path through all ZIP codes. In computer science, this is called the Travelling Salesman Problem (TSP), and so I decided to make this the Travelling Presidential Candidate Map."
Robert Kosara offers different variations on his Scrible map, including one that shows a presidential candidate's map of visits during his campaign.
