The Prefuse toolk开发者_开发知识库it haven't been updated since 2009 and the last build is from 2007. Is there any other Java visualization packages as powerful as Prefuse but has active community support/development?
Protovis is the successor of Prefuse (and now, D3 is under active development). Protovis-Java is a partial implementation of the Protovis toolkit in Java. There's a nice example gallery, but I have no experience with the Java side.
As an alternative, you might consider Processing, with some example of use in Java here, or its Javascript counterpart, Processing.js. There were even a port for Scala + Processing: Spde.
