One of the many emails we receive pointed to this interesting visualization applet. After entering a website address, the applet generates a visual display of nodes, connectors and connections. Clusters illustrate the networks of related content. Aside from the pleasant visual display, the paths illustrate the fluidity and relative ease of movement from one area to another. Centralized, hierarchical information appears as a giant ball. Decentralized clusters usually indicate capacity for quicker switching from one content area to another. Try it yourself at http://www.aharef.info/static/htmlgraph/ . The applet takes time and is likely to degrade local system performance while running.
The following are from two sites we worked on.
This second site has unique sections designed for specific groups of stakeholders and functions. It also contains rich core of public content.
