The edge-repulsion LinLog drawing shows on a global scale the three large economic areas of the world: Northern and Central America, Eastern Asia and Australia, and Europe. Within Europe, the positions of the countries roughly resemble their geographical locations, reflecting that geographically close countries tend to trade more. On a more local scale, the drawing groups the Northern European countries (Norway, Sweden, Finland, Denmark), and pairs countries like Spain and Portugal, Australia and New Zealand, Malaysia and Singapore, and China and Hong Kong.
The drawings of the Fruchterman-Reingold model and the node-repulsion LinLog model place the economically large countries very close to each other in the center, and the smaller countries towards the borders. (This is difficult to recognize especially for node-repulsion LinLog because the large countries are extremely close.)
