Where material comes from and goes

The extraction geography of the six categories and how far each travels to the consumer, category by category on a real map.

The same raw-material flow, drawn as six separate maps: each category (energy, minerals, agriculture...) traces its own geography, line thickness is the size of the flow. All six are drawn to the same scale, so the maps can be compared directly - if one category's lines are thicker than another's, that category is bigger.

The routes carrying the most physical weight (sand, gravel, crude oil).
