There are quite a few graph tools that visualize the structure of an entire website. htmlgraph is one that visualizes the structure of the HTML DOM-tree of a single page. What makes it interesting is that it color-codes the different HTML elements:

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

Here are the DOM-tree graphs of a few popular German blogs, and of mine:

The part below the single green dot is my sidebar, above it is the main pane: concise, things inside divs structured by lots of p-tags, lots of links in each blog posting.

Similar structure with sidebar and main pane, the latter looking pretty clean. The top right cluster could be the "Other recent entries" part at the bottom of the main pane.

The big center cluster should be the li-structured sidebar.

Der Name ist Programm - does exactly as it says on the tin ;-) Red dots are table markup.
