Algorithms to characterize the number of triangles in a graph.

triangles(G[, nodes]) Compute the number of triangles.
transitivity(G) Compute graph transitivity, the fraction of all possible triangles present in G.
clustering(G[, nodes, weight]) Compute the clustering coefficient for nodes.
average_clustering(G[, nodes, weight, ...]) Compute the average clustering coefficient for the graph G.
square_clustering(G[, nodes]) Compute the squares clustering coefficient for nodes.
generalized_degree(G[, nodes]) Compute the generalized degree for nodes.
