Map of country cooperation networks, with 40 nodes and 104 links, in MRE from 1995 to 2021. Each node represents a country, with the size of the node proportional to the number of articles published. The colored rings in each node indicate years of publication, ranging from cool (early) to warm (recent); purple trims appear in those nodes with higher betweenness centrality. Each link represents the connection between nodes, with the thickness of the links indicating the strength of the cooperative relationship. MRE, magnetic resonance elastography.
