This is either a useful tool or a fun toy. Websites as Graphs is a Java applet that renders your website’s (X)HTML structure as a graph of colored dots.
You enter a sites’ URL into the form, and the applet puts a black dot on the screen (representing the root <html> element). Quickly, more connected dots expand outward. Each dot is color-coded to match a group of elements. The blue dots are links, the red ones are tables, etc. The graph shown to the right shows this site (note the lack of red dots ).
It’s fun to enter a bunch of your favorite websites and compare them (maybe it is a toy rather than a useful tool…), and compare them to your own as well. Try it out, it’s fun to watch if anything.
