The topic map of the CIA World Factbook was enhanced by data on production and consumption of oil, gas, and energy, as well as on export commodities.

Due to the subject-centric mapping, any country named for a particular export commodity is now linked with all other countries named for the same commodity. Therefore, it takes just a mouse click to find out, for which countries the CIA mentions carpets as relevant export commodities.

Answers to strategic questions on carpet exporting countries may also be easily retrieved. For instance, find out which of the carpet exporting countries has the highest oil production by setting a text filter ("carpets") on the locations overview, and sorting the remaining countries by the respective property.
