These two diagrams are the MFA scheme set-up for the research followed by the MFA diagram for PET flows in the year 2007.  In the sankey diagram, the dashed lines indicate upper bounds for highly uncertain flows.  I like how the import and export fractions of each flow are represented by small slivers peeling away from the main flows.
