This map shows, on a Bertin projection, a selection of the largest container ports in the world. Their Urquhart graph is computed by d3.geoVoronoi and displayed in red geodesics.
(Re: the obvious geographical bugs: the dataset is composed only of the coordinates of ports and contains no knowledge of the shape of continents – the network thus happily crosses through land.)
