Just found a great review of different visualization tools for communities.

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.

When I first tried out the NetBeans GUI Builder Matisse, I was as skeptical as I would be with any Java GUI builder. They never turn out to be exactly what you’d expect; even IDEA’s designer, simplifying GridBagLayout to just a few clicks and properties, doesn’t have the same feel as Visual Studio 2005.

Whatever my feelings were before trying Matisse, I was surprised after using it: Not only did Matisse do everything I expected a GUI editor to do, it even offered new features that really made me raise an eyebrow wondering, “Why did no one else think of this before?”

In this article I will present the features I enjoyed best in Matisse, and then suggest a few features I would like to see in future releases.
