Summary
An isochromic map of the world population, superimposed on a pastel-color background that shows land, water, and borders.
Everything in black is population.
Note: Some border lines may be completely obscured by populations (especially India's borders with Bangladesh, Pakistan, and Bhutan). Still better than the opposite (letting the border lines obscure the populations).
Note: Be careful not to confuse small blue dots (lakes) for small black dots (population). In the next version I'll try to make the blue parts lighter (or erase small bodies of water) so this doesn't happen.
Methodology
Image generator code:
