The following data visualization was done using D3.js, custom data and runnable.com
The data was gathered from http://www.trademap.org/Country_SelProduct_TS.aspx?nvpm=1|||||08|||2|1|1|2|2|1|2|1|1
The countries were selected as Top 10 food importers in Spain (where I live). FYI, US, Spain and Chile are in Top 4 food exporters in the World.
The visualization shows interactive relationship between countries and the bigger the base of the connection the bigger the export from that county to the one the relationship ends.
