I'd like to implement icons like those in the figure below to denote, for instance, the level of satisfaction of a certain requirement.
I didn't find such icons in any icon pack. I also tried \mathrel
but the circles are not perfectly concentric at the end. How can i solve?
Moreover, is there a way to create them deciding the ratio between the black circle and the white one?
Thank you in advance.
