Interesting graphs to try out (note: these all use a maximum θ of 360 and an interval of 1): - Cardioid: 80 + (-80) * sin(1 * θ) - Convex: 110 + 55 * sin(1 * θ) - Rose petals: 0 + 130 * sin(5 * θ) - Inner loop: 50 + 100 * cos(1 * θ) - Rose petals w/ inner loops: 50 + 100 * sin(7 * θ) - Meeple: 100 + 20 * sin(5 * θ)
