LaTeX digraph generator
In this site you can generate a latex tikzpicture of a digraph (directed graph). Select the number of nodes in your digraph and the edges to draw. Move the nodes around with your mouse until you find a nice shape. Select the way to label your nodes (edge labelling isn't supported yet). And finally, generate your latex code.
This tool is in development and might not be useful. It is also possible that a "nice" representation of your digraph isn't possible.
