The crystalline structure of HTML

Reddit sent me to this Web site, which analyzes Web design using crystal-like tag-association graphs. First, this guy SO needs to open source the code he used to produce these graphs, because everybody could use a nice, abstract analysis of teh Web design. Second, the comparison of MSN and Google is so strikingly obvious under his model that I had to show it to you.

Startling, isn't it. The comparative simplicity is obvious, not just visually, but structurally. Windows bloat writ large as a function of corporate design philosophy. I'm almost scared to see what this code would say about TR--which is exactly why I wish we could.
