The graduated symbol schematics below have been created in R (using ‘symbols’). They plot combinations of country territorial and population sizes. Instead of dividing for population density we multiply for a function of both. The total of box areas is held constant to enable proportional comparison.

We might consider territory a very rough proxy for natural resources at macro level – some studies use this approach. Ever wondered how the world divides up in terms of human and physical resources? Will there ever be a day when the G8 and P5 must make way for the R5?
