Mass, value and logistics each peak in a different corridor among the 4,919; the priciest one (Canada to the US, crude oil, $0.10T) isn't the heaviest.
Each row is a "corridor": one resource's annual export from one country to another - its volume, the distance it travels, and its dollar value at the source. Each of the three measures below peaks in a different corridor. All 4,919 corridors are below, searchable and filterable.
