Since tags are nested in other tags, they are arranged in a hierarchical manner, and that hierarchy can be represented as a graph. see cnn, boingboing, Yahoo, msn, google, and others. Or you can also get your own site graphed, or someone elses site.
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
gray: all other tags
