A contact graph is a type of graph used to represent relationships and interactions among entities, typically in the context of epidemiology, social networks, or communication networks. In a contact graph: - **Nodes (or Vertices):** Represent individual entities, which could be people, animals, or any other units of interest. - **Edges (or Links):** Represent the relationships or interactions between the nodes.
