Visualization of the structure of popular sites

Every day we browse many sites.
The structure of these sites is reflected in the HTML code.

Sala, the author of this blog , wrote a very interesting applet that analyzes page tags and renders them according to the following specification:


For example, visualization msn.com. Pretty branched structure, with a lot of pictures:

msn.com


And here is the structure of apple.com. Pretty simple structure, except for the array of yellow dots (this is a dropdown menu)

apple.com

Simple and ingenious Google. I was not able to find a simpler structure:

google.com

And the applet itself can be viewed here .
