Figure 1

Computer Science co-authorship community structure from 1975-2020. Plots show community metrics based on the Label-propagation algorithm for the Largest Connected Component (see text). (A) Number (in thousands) of communities per year. The dashed line highlights the 39,998 communities with size ≥3 in 2010. (B) Community size distribution (i.e., number of researchers per community). (C) Distribution of the number of internal papers (all authors within the same community) per community. The colour bar represents the proportion of communities with a given size and a number of internal papers. The inset panels of (B) and (C) show the frequencies of size and number of internal papers for the example year (2010)
