Description

Belief-propagation is a way to represent probability of events with a graph. In order to better understand complex Belief-Propagation models tested with our simulator we have identified a strong need for a simple visualization tool that will grant us insight of the tested graphs.

Requirements for the tool were:

• Visualize graph topology.

• Visualize information sent between graph nodes.

• Visaulize process progress.

• Visaulize inner node state and information.

• Visaulize nodes communication.

Framework

Since the simulator was written in Java, I have looked for a simple Java visualization framework that will enable to meet all requirements. Moreover, this will enable the tool to run platform free (and as a goal - to run as an Applet).

We chose JUNG (Java Universal Network / Graph) as our framework since it is both simple and robust.
