These pictures were made using inequalities (inequations).

For example, the blue area in the picture below is the graph of

the inequality cos(2y) cos(y+sqrt(3)x) cos(y-sqrt(3)x) < 0.

Although this picture looks like a curve plot, it is not a curve plot.

It is a part of the graph of an inequality ( fun(x,y) <= 0 ).

The original graph of fun(x,y) <= 0.
