This sets of three graphs compare degree distribution in the three one-mode networks of co-attendance at the meetings of the Shanghai Rotary Club under President Petit's (1919-20), Fitch's (1930-1) and Harkson's (1938-9) terms. The original datasets and the resulting graphs are available in the "Tables" and "Trees" section, respectively.

NB We used Cytoscape Network Analyzer application to make these graphs.
