Fig. 5: Geographical distribution of hub ports in the GLSN.
From: Modular gateway-ness connectivity and structural core organization in maritime network science
Here the three plots show the gateway-hub ports (i.e., ports with B ≥ 1.5), provincial-hub ports (i.e., ports with Z ≥ 1.5), and connector-hub ports (i.e., ports with P ≥ 0.7), respectively. Ports are colored according to modular communities. In each plot, triangles denote ports which have only that particular type of hub role under investigation; circles, ports which have one additional type of hub role; crosses, ports which have all the three types of hub roles. Outside-module degrees (B), inside-module degrees (Z), and participation coefficients (P) of the hub ports are reported in the source data. Source data are provided as a Source Data file.
