Sonia++
What is Sonia?
From the Sonia site:
SoNIA is a Java-based package for visualizing dynamic or longitudinal "network" data. By dynamic, we mean that in addition to information about the relations (ties) between various entities (actors, nodes) there is also information about when these relations occur, or at least the relative order in which they occur.

Why Sonia++?
Sonia does not handle many-slice, many-edge graphs efficiently in either memory or computation. Furthermore, there are many real-world cases
in which properties of dynamics graphs can be leveraged to obtain order-of-magnitude decreases in run-time. For large data sets, such a magnitude
decreases is the difference between feasible and infeasible. As a result, there is a pressing need for continued development and redevelopment of
the internal Sonia engine.
What can I get?
For now, the only public release is a binary of the latest development version of Sonia. This code was compiled from the CVS snapshot as of
March 11, 2009, and will serve as the model for Sonia++.
