I have a circle mesh that I'd like to be opaque for most of its surface, but slowly fade to transparency at the edges.
My current node setup is this: Node setup

But my result is a mostly transparent circle that is more transparent around the edges: Preview result

Any small adjustment to the "Blend" setting causes the preview sphere to become either pitch black or invisible. Even if I did find the correct setting, I don't think it'd work properly because I'd like it to be only the edges that fade, not the entire circle.
The end result I'd like is closer to this (badly photoshopped): What I want my circle to look like Any help you can give is very much appreciated!

You can use a RGB Curve or a Color Ramp node to control the transition :

with rgb curve

with color ramp
