I agree that software lacks this visual language -- I always find English a better architectural description language than UML, though I am not particularly happy with either. I think the reason is that computer programs are documents -- things constructed in a language. Someone might conceivably write a good summary of, say, _War and Peace_, but a diagram of the book would only be useful for illuminating certain aspects of the story.
