Fig. 5From: Graph reconstruction using covariance-based methodsIllustration of the four different graphs that have been used in our study. Shown are the adjacency matrices of the graphs and their corresponding graph topologies. a Chain graph with maximum degree of 2. b Cluster graph which consists of three disjoint subgraphs. c Scale-free graph (Barabasi-Albert graph). d Hub graph, also known as a star graphBack to article page
