Visualization is a technique to graphically represent sets of data. When data is large or abstract, visualization can help make the data easier to read or understand. There are visualization tools for search, music, networks, online communities, and almost anything else you can think of. Whether you want a desktop application or a web-based tool, there are many specific tools are available on the web that let you visualize all kinds of data. Here are some of the best:
Visualize Social Networks
Last.Forward: Thanks to Last.fm's new widget gallery, you can now explore a wide selection of extras to extend your Last.fm experience. The gallery hosts widgets for your desktop, for the web, for social networks, and much more. One of the better tools in the gallery, last.forward, is open source software that lets you map out any last.fm user and their connections. The web site for the software appears to be in German, but the "Download" button still works. And once it was downloaded and installed, I had no trouble using it myself.
Friends Sociomap: Friends Sociomap is another Last.fm tools that generates a map of the music compatibility between you and your Last.fm friends.
Fidg't: Fidg't is a desktop application that gives you a way to view your networks tagging habits. You can see what kind of music your network is into, or what kind of pictures they are taking. The Fidg't Visualizer allows you to play around with your network. To use Fidg't, you interface with the Visualizer through Flickr and LastFM tags, using any tag to create what they call a "Magnet." Once a Tag Magnet is created, members of the network will gravitate towards it if they have photos or music with that same Tag. You can also search through the network for certain users, and see their recent photos and music. The Fidg't interface is beautiful, too.
The Digg Tools:
Digg.com has some of the best web-based visualization tools on the net, so they're a must for any visualization list.

- Swarm: Digg Swarm draws circles for stories as they're dugg. Diggers swarm around stories which makes them grow and get brighter.
