My blog is beautiful on the inside

This is what this blog looks like in graph form. But what does it all 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

Some of the ones on flickr are awesome. I bet yours looks cooler.
