Contiguous USA State Adjacency Network
A USA state border adjacency (geographic network) dataset of 49 nodes and 107 edges, collected by KONECT. Each record contains directed: False, weighted: False, signed: False. Geographic adjacency network of the 48 contiguous US states — nodes are states, edges connect bordering states.. Suitable for geographic network analysis, graph coloring, planar graph benchmarking.
