Flow Map of PVA

[Vamsi]

As PVA grows with no of topics, keeping up with flow data diagram with new topics and connects is becoming a manual task.  Would be nice to see an overview mapping diagram of how all topics talk to each other. Essentially a flow diagram would be helpful since PVA knows all connections.

Featuring an option to inquiry and/or print a connection flow diagram on new added topics, maybe optimum.
