Visualizing data redundancy

http://www.soatrader.com/10-visualizing-data-redundancy.html

In one of my earlier blog entries I elaborated redundancy in federated information systems. The following picture illustrates such redundancy. Cluster map technology is used there to represent overlappings of entity attribute clusters. Each cluster represents entity attributes in an information system description. Overlapping areas represent entity attributes, which are potentially redundant, since they appear in several clusters at the same time.

The clusters were generated with inhouse analytics software, while Aduna Cluster Map ( http://www.aduna-software.com/...clustermap) was used for visualization.

So what are you going to do now Aduna pulled their open source license? I was about to use cluster maps for a project just as I discovered their terrible deed!!!!!

All this happened fast... Which alternatives have you considered? BTW there are some quite nice open source topic map visualization tools available.
