Hi everyone,  
Is there a way I can plot a circle giving a center position and the radius?  
I couldn’t find any filter to properly do it

Try the `Ellipse` source from the Sources menu. A `Ratio` of 1 (default) gives a circle.

Calculating as R = （x^2+y^2)^0.5, then contour it may be an alternative method
