World map VII - continents

Merging Natural Earth's countries dataset to create a map of continents yields a map that does not correspond to any of the alternatives listed by Wikipedia for subdividing the world into continents.

This map is similar to the 7 continents convention, but it portrays the Russian Federation and French Guyana (plus many small islands) as part of Europe. A curious continent called "Seven seas (open ocean)", grouping a few islands, can also be found in the dataset.
