Using data extracted from this wiki page (mirror), an initial multitude of grey dots are added, one for each country. No connections are present. The more colorful part of the graph is during the development of CONected, a global oligarchy mapper.

Next connections are added. If it looks too connected, it is. There are several entries for things like the European Union and France and England had connections all over the place. The Antarctic connections are also confusing.

After going through the initial data, editing out the suspect connections, and then teasing a few key nodes into place (Russia, China, Egypt, and India), you end up with a distorted, though recognizable, map. Here is the edited data used to make this graph.

No interface, but it gets the job done.
