From: The nuclear network: multiplex network analysis for interconnected systems
An illustrative multiplex network of proliferation-relevant determinants, with layers from top to bottom showing the NCAs, alliances, conflict, and trade relationships between nodes. Panel a shows a schematic network representation, where the nodes represent states. These nodes participate in all network layers, but the relationships between nodes (edges) are unique in each layer based on the relevant interstate relations. Panel b shows the full network representation of the model for the year 1980, built using open-source data
