It only lays out as much of the graph is visible plus a little more, not the whole graph, and it doesn't use any global analysis. The reason for that is speed. Gitk is usable on a repository with half a million commits, such as the linux kernel, and to achieve that we can't afford to do wait until we have all the commits read in and then do some computation over the whole topology; it all has to be done incrementally. Also, the underlying git log sometimes gives gitk a parent commit before one of its children, and when that happens the topology has to be modified and thus the graph does too, if any topology that has already been drawn gets modified. As long as the graph correctly shows the relationships between commits, it has achieved its purpose. If you (or anyone) can come up with improvements that make it look nicer, that's great, and I'll consider them as long as they don't slow down gitk on large repositories to any noticeable extent.
