Studying how peers come and go in a model of a peer-to-peer overlay network and how it effects the distributed routing information can be a complex task. It usually gets to be a complex task even for a relative small network. Means for visualizing graphically the events and changes in an overlay network would be helpful for understanding, developing, verifying and demonstrating such networks. This report is the result of a short study towards designing and implementing such a visualization tool for the Chord protocol.
