Question 6

A pirate’s large square treasure map is divided into small squares. To encode it: (1) represent a uniformly colored region by a square of that color; (2) otherwise draw a circle and divide the region into four quadrants in the illustrated order; (3) repeat until all regions are encoded. The four construction examples establish the quadrant order and sizes.
