Flow maps


The map that we are focusing on here is the top one which shows China's crude oil trade forecast through a flow map. The arrows in red indicate that China is net importing and the only one in green, with Japan, is the lone net export for China and oil. This indicates that China is in high need for oil and is not producing nearly enough oil to support themselves. This map does not use a desire line as those are mostly used in flow charts that deal with travel rather than import/export.
