Mass - value explorer

Sand and gravel: 45 Gt a year at just $5 a tonne; gold: only 3,300 t a year at $45M a tonne - free exploration.

Analyze the data in depth using different visualization models.

Each point represents a resource: the horizontal axis is annual extracted mass, the vertical axis its dollar value at the source, both logarithmic because the gap between them is enormous. Example: sand and gravel is extracted at 45 Gton a year but sells for only $5 a tonne; gold is extracted at only 3,300 tonnes a year but sells for $45 million a tonne - sand and gravel dominates by mass, gold by value.
