Flexion and Skewness in Map Projections of the Earth by David M. Goldberg, J. Richard Gott III

Winkel-Triple got a 4.5629

numbers != science

I decided to go about it backwards.
I started with a kind of artistic approach.

I visualized the best-looking
shapes and sizes.

Then I figured out the mathematical formula to produce that effect. Most mapmakers start with the mathematics.

Arthur H. Robinson

when you don't create things,
you become defined by your
tastes rather than ability.
your tastes only narrow &
exclude people. so create.
_why

Things you Create

f(x, y) → x

g(x, y) → y

simple technology: Canvas, GitHub, Javascript

uses, loves, enjoys eval and has no regrets

good enough for Mercator, Albers, Equilateral, Azimuthal
