http://www.graphviz.org/ is the place to start for dot related materials.
I should point out here that dot is a file format rather than an
application. I don't recall finding a really good program for drawing dot
graphs, but lots of tools for laying them out/viewing.

I think (no time to check) that a simple dot description of this might
look like:

digraph Workflow {
	one -> two;
	two -> three;
	two -> four;
	three -> five;
	four -> six;
	five -> seven;
	six -- seven;
}

You can add all sorts of other info too (descriptions, etc). I just have a
plane to catch right now :)
