I have written a blog post on how one can look at radial gradients, and 
the effect of having the focus on or outside the circle:


I have included several examples and diagrams, but if there is still 
anything that is unclear, feel free to say so and I'll update it.

The post also gives some suggestions for dealing with the instability 
that occurs when the focus (zero-radius point in my post) is on the circle.
