GraphViz Examples by Natalie

GraphViz is a nice, extensible tool to draw graphs, trees, diagrams, among others. It's scripted using a simple language called DOT, which reads a lot like text in plain English.

I've published a handful of examples, and an unfinished guide here on this website. You may also find the official user documentation useful.

A taste of DOT (refresh for another!)
