area	(optional) Area. Should be an sf or sfc object containing one (multi) polygon
n_circles	Number of rings including the central circle. By default 5, unless area is specified (then it is set automatically to fill the area).

distance_growth	The rate at which the distances between the circles grow. Only applicable when distance is one number and n_circles > 1. See also distance.
