We’ve all had that experience: a bunch of directed graphs in our heads that we’ve been thinking about rendering. However lacking in the time and expertise to do so, unrendered they remain.
However, If you’ve got a little patience watch this screencast I recently made. It walks you through using ATT’s GraphViz tool to draw directed graphs. I go through formatting a graph using GraphViz step-by-step so that you can see exactly how do it for yourself.
