From: Identification of multidimensional Boolean patterns in microbial communities
Example of multi-layer network. Multi-layer network visualization of two- and three-dimensional patterns in attached keratinized gingiva samples. The network contains two types of nodes representing OTUs (circular) and three-dimensional patterns (circular with a triangle). Node colors reflect different taxonomy assignments at phylum level, and node sizes are proportional to the average relative abundance of the microorganism across samples. Capital letters inside square brackets represent the lowest taxonomy level identified for each OTU: G, genus; F, family; O, order; C, class; and P, phyla. The color of edges indicates relationship type: blue with a black arrow (one-way relations), red (co-exclusion), light green (co-presence), dark green (3D co-presence), and orange (type 2 co-exclusion)
