Hypothetical viral genomes in squares represented by two types of networks. A) Bipartite network shows which gene families (in circles) are shared by the viral genomes (V1–V4). B) The network in (A) is simplified into a monopartite network between viral genomes with the thickness of the edges representing how many gene families are shared between genomes. This figure was recreated from an article by Iranzo et al. [64].
