The Sketchviz site lets you enter GraphViz code and get out something that looks hand-drawn. I decided to try it on some of the GraphViz diagrams I’ve made for this blog.
Here’s a diagram from my post on Rock, Paper, Scissors, Lizard, Spock.
The Sketchviz site defaults to Tinos font, which does not look hand-drawn. Maybe you’d want that sometimes: neatly typeset labels and hand-drawn boxes and arrows. In my case, I thought it looked better to use Sedgwick Ave which looks closer to handwriting.
