Recently I needed to crank out a visual sitemap (or is it a directory tree?) from a rather large site and had a devil of a time finding decent tools to help. Everything I found in my search was either too costly, too complicated, or too unattractive for my purposes. A case in point was CSS Diagrams—a damn fine piece of work (and free), but it really didn’t suit my needs. But it did give me an idea. Why not roll my own sitemap diagram in HTML and CSS?
