How to plot a hollow circle with gradient/fadeout/glow in Matplotlib?

Time:11-17

I would like to plot a circle of a given outer radius which would have an empty hole of a given inner radius. Then the resulting ring would have a fade-out gradient fill, however starting not from the center of the circle, but from the border of the inner circle. In Photoshop it's called "glow", from what I know. Is something like this possible?
