nice one. Dot (both the layout engine and the graph DSL) is used in OmniGraffle, so you can import the dot files like you made into OG and edit them further, either manually or via OG's scripting interface and then for instance, quickly convert text inside a node to a link to a suboordinate graph (ie, the top-level graph might describe a large project, and each node in that graph, might represent a "sub-project"--hence you can represent a very large project as a hierarchy of graphs, eg, one per sub-project, but that still roll-up to a single top-level. This is a core feature in OG and trivial to do
