Too many dimensions in software to draw it properly on a flat screen. Software is more like a hairy graph where each node is connected to tens of other nodes, and automatic tools can't figure what nodes are important. Even with a 3D VR immersive interface, that's still a nearly impossible task. Edit: and layout of components is just one thing, the same components would look very different on "message flow" and "initialization sequence" diagrams, while combining both diagrams into one would create a mess. In the future mainstream languages will probably have annotations to describe "role" of various things, specifically to enable diagram generators.
