One-mode undirected network of US state contiguity (Meghanathan 2017)

Source: R/data_ison.R

This network is of contiguity between US states. States that share a border are connected by a tie in the network. The data is a network of 107 ties among 50 US states (nodes). States are named by their two-letter ISO-3166 code. This data includes also the names of the capitol cities of each state, which are listed in the node attribute 'capitol'.
