title: How to visualize/draw automata in ocaml?
body: <p>I am doing composition of automata. So at the end of that, I want to draw the composed automata also. So are there any libraries for that in ocaml? or are there ocaml wrappers written for any graph visualization tool? I have googled for it but didn't get much for ocaml. Any comments on ocamlgraph? I will get more than 100 states in composed automata.</p>
