Found this website http://www.aharef.info/static/htmlgraph/ the other day. Basically you enter the website, and what it did here was a representation of the aainter3 blog in this rather beautiful graph...
What do the colours mean?
blue: for links (the A tag)
red: for tables (TABLE, TR and TD tags)
green: for the DIV tag
violet: for images (the IMG tag)
yellow: for forms (FORM, INPUT, TEXTAREA, SELECT and OPTION tags)
orange: for linebreaks and blockquotes (BR, P, and BLOCKQUOTE tags)
black: the HTML tag, the root node
grey: all other tags
Cool innit?
