Role

gateway

Virgin Islands (U.S.) acts as a gateway because its network-relative degree, reach, or gateway-share signal is elevated; the gateway-share signal is around the 82th percentile.

Role labels are network-relative classifications derived from degree, reachable-country count, bridge coverage, and gateway concentration within the country-topology graph.
