I'd like to draw a circle over a MapView to show all the points that distance e.g. 20 meters from a point. I searched on the documentation but I found only ways to draw polygons given a set of coordinates, while I need a way to draw a circle given a point and a radius (in meters). The Maps app does exactly what I'd like to do when showing signal precision (drawing a cirle around the point, representing precision approximation), so I guess there is a "right way" to do that.
I thought I could write a function to calculate the coordinates of points of the circle from scratch, but it would be difficult to mix longitude/latitude with plain meters...
Thank you
