This is a meme that is really interesting. Generating a graph of your website based on the tags used in the content. It is quite interesting to see the differences between a simple page containing very little markup like the front page for my domain as shown below compared to the amount of markup found in this blog.
Go to http://www.aharef.info/2006/05/websites_as_graphs.htm to read more about the graphs or visit the graph generator here. Then post your graph on your blog or on flickr taged as websitesasgraphs
