A visualization of the interactions that were described in the above text on scientific interactions. It is seen that for every pair of investigators, there are multiple paths connection them. This is generally thought to be a sign of a robust network (Albert and Barabasi, 2002), since it ensures that losing a single node, or breaking a single connection, will not break the network. Networks of interacting genes tend to be of this sort (Ravasz et al, 2002). For more, see the Network Structure of the NCDBN.
