The plot shows the aggregate number of susceptible, infected and recovered individuals in the network as a function of time. In each case the nodes represent locations; the grey nodes are homes and the black nodes are work locations. Hospitals are represented by blue nodes. Individuals are represented by links between a home and a work location. The color of these links represents their infection state: Yellow links represent susceptible individuals, while red links represent the infected across the infected compartments and green links represent the recovered.
