A polar graph is a math concept where the distance r from the center of the graph is determined by an equation. (r=1 would be a circle. r=sin(angle) makes loops)

Normally you start the angle from 0 and go all the way around to 360 degrees incrementing by some small amount. When you skip say every 80 degrees, you get something interesting. A Maurer Rose

Trigonometrics takes this maurer rose idea and puts you in control of every aspect of the design. The size, location, color palette, amount to skip, and a multiplier for the angle (to determine how many petals your maurer rose will have).
