I created this from Desmos.com Just change the mode from Cartesian to polar.
I graphed a polar rose by using r= and a number that changed how big the circles will get. I used r=acos(n*theta) to get spiral circles. Then I also used r=asin2theta to make petal like circles. When using r= there is a slider under that can make it bigger.
I created this more darker and bigger rose using r=2, then more r=any number. Then used r=acos(n*theta) and r=asin4theta. I used the sliders to make the spiral circle and normal circles bigger for this rose.
