SoNIA (Social Network Image Animator) is a Java-based package for visualizing dynamic or longitudinal network data. View dynamic network data.

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.

SoNIA Features:
1. loads dynamic network data as node and arc events
2. specify binning and aggregation rules to divide events into networks
3. apply network layout algorithms to position nodes in each time slice network
4. export animation of network as a movie file
5. specify graphics settings for visualization

In addition, we hope that SoNIA will have other uses. One of the most important is for it to work as a platform for the development, testing, and comparison of various static and dynamic layout techniques. Because of this, We have attempted to code SoNIA as an OpenSource project in a modular fashion so that the various layout techniques and tools are fairly interchangeable, and they can all draw on a common set of utility functions for common network and layout operations.

Another mode of use that SoNIA supports is that of a "browser" for time-based network data. Our intention is to make it as easy as possible for users (us) to visually inspect sets of relations in large datasets at varying temporal resolutions and degrees of aggregation.
