Hierarchical properties of real networks.

We show the order (), average degree (), and global reaching centrality for the original () and for the randomized networks (). References to data sources are included. Suits next to the GRC values show comparison to the randomized networks: whether the original networks are more hierarchical than their randomization (club suit) or they are more egalitarian (diamond suit) with a 98% confidence level. The meaning of edges is also indicated.
