Figure 2. Concepts of networking applied to microbiome data. (A) Example of a network constructed from a relative abundance table of bacterial genera, where each node represents a bacterial genus within the microbial community and each blue line represents a pairwise relationship. (B) The same network structure, with green and red lines highlighting positive and negative interactions, respectively. Node size is proportional to the relative abundance of each bacterial genus and edge thickness to the force of relationships. (C) Microbiome network with hub nodes highlighted in red. (D) The microbiome network is grouped into five distinct modules, highlighted by different colored circles. The image was created using Cytoscape.
