Summary

Description234-Fingertree-Example.svg
English: I created a 2-3-4 tree of height 4 with random insertions and deletions. I tried to target it to have around 40 nodes, looks like it came out with 37 if I counted right. I then manually converted it into a finger tree by the "spine-straightening" steps in Hinze and Paterson (2006), "Finger Trees: A Simple General-Purpose Data Structure." I dumped the result to GraphViz, colored it with some colorblind-friendly backgrounds, and nudged some nodes down a level to give a cleaner aesthetic proportion.
