This chart depicts the sources of American oil imports. While the  United States gets about 45% of its oil from the Middle East and North  Africa, these regions hold over two thirds of the oil reserves  worldwide.

Export data for oil from Lybia, shown as a pie chart has been  converted to a Sankey diagram. It gives a good idea of where most  exports go to. Created with e!Sankey, using a Wikicommons world map as  backdrop.

It was new to me that “Libya has the largest proven oil reserves in Africa” with 41.5 billion barrels, and estimated net exports of 1.525 million barrels per day in 2006.

The underlying map is a crop from a World map found on Wikicommons. I think it could be a little more transparent though…

The cutting of two submarine internet cables in the Mediterranean Sea at the end of January, and another one in the Persian Gulf a few days later, was widely reported in the news. The cuts affected internet services and call center operations in large parts of the Middle East and India, sparking discussions about emergency backup plans for offshore software development.

This reminded me of the internet traffic maps I had seen on the Web before. These are available as traffic load maps as well as bandwidth capacity maps of the backbone infrastructure.

Indeed these maps can be considered as fine examples of Sankey diagrams, with bi-directional (or non-directional?) arrows whose magnitude represent the bandwidth of the transcontinental internet cables. Additional arrow colors could be used, for example, to represent ownership or operation of the cable by different companies.

At the same time the Sankey maps may also serve to indicate communication technology development in different world regions.

BTW, if you want to stick one of these maps prominently on your office wall, they are available as posters here.
