I am studying a number of empirical networks and will have to find a clear way of illustrating various structures and measures of centrality to an audience that may have very little knowledge of graph theory.
I would like to illustrate the various concepts with a popular model similar to the Medici network, but using a directed preferential growth network. I am not too worried about other structural traits for now (weakly / strongly connected, centralized, decentralized etc.) but it would very nice if it were salient to policy / political scientists or economists. Most ideal would be a communication network.
Any examples would be greatly appreciated. Thanks.
