The following plot shows multiple features of the Joukowski transformation. There are simple zeros at since the colors converge at those points and cycle around the points from blue to green to red in the counterclockwise direction, consistent with the legend. Similarly, there is a simple pole at where the colors converge but cycle clockwise. There is also a saddle point at and the branch cuts occur at the red-blue boundary:
