English: "Edges link ARGs to the genera which their contigs were taxonomically assigned to. Only flanked, non-plasmidic contigs were used. The backbone algorithm was used to compute the graph layout. Color and thickness of edges denote the number of observed taxa-gene co-occurrences. Nodes are ARGs and genera which are visualized as grey boxes and colored circles respectively. Node size denote the centrality of the individual nodes to the overall network. Smaller subgraphs were manually moved for space efficiency, so relative distances between those mean nothing." "A network graph of genus-ARG co-occurrence revealed a major separation according to high-level taxonomy (Fig. 4). See Supplementary Fig. 13 for a version with more annotation. Several proteobacterial genera (purple circles) including Klebsiella, Escherichia, Pseudomonas and were each host to many different ARGs. Some of these were shared with other Proteobacteria (on edges tying the purple cluster together), while many others were uniquely seen in their respective genera (unconnected edges extending outside the cluster)."
