The diameters and modularities of 13 real networks.

1The network of coappearances of characters in Victor Hugo's novel “Les Miserables”. Nodes represent characters and edges connect any pair of characters that appear in the same chapter.
2The network of common adjective and noun adjacencies for the novel “David Copperfield” by Charles Dickens. Nodes represent the most commonly occurring adjectives and nouns in the book.
3The network of frequent associations between 62 dolphins in a community living off Doubtful Sound, New Zealand.
4The network of political blogs. Nodes represent blogs and edges are the links between blogs.
5The network of scientists posting preprints on the high-energy theory archive at www.arxiv.org, 1995–1999. Nodes are authors and edges connect coauthors.
6The network of American football games between Division IA colleges during regular season Fall 2000. Nodes are teams and edges connect teams that contest in a game.
7The network of the Western States Power Grid of the United States. Nodes are power plants, stations and households, and edges are powerlines.
8The network of scheduled air line connections in United States, 2005. Nodes are airports and edges are scheduled direct flights.
9Electronic circuits. Nodes are electronic elements and edges are electronic connections.
10The protein-protein interaction network of the budding yeast S. cerevisiae. Nodes are proteins and edges connect proteins that interact with each other.
11The neural network for the worm C. elegans. Nodes are neurons and edges link neurons that connect.
12The transcriptional regulatory network of the budding yeast S. cerevisiae. Nodes are genes and edges connect genes that regulate one another.
13The metabolic network of the bacterium E. coli. Nodes are metabolites and edges connect metabolites that can be converted by a biochemical reaction.
