title: How to draw a HSV color wheel using matplotlib
body: <p>is it possible to draw a HSV color wheel using matplotlib in python? I want to get an HSV color wheel like the following image as a reference image of the optical flow. In this image, every HSV color can be expressed as a vector where the direction is encoded in hue and length is encoded in saturation so that I can easily compare it with optical flow. I have searched online but I could not find a satisfied solution. Any help will be grateful!</p>
