zb_doughnut( x = NULL, area = NULL, n_circles = NA, distance = 1, distance_growth = 1 )
Number of rings including the central circle. By default 5, unless
area is specified (then it is set automatically to fill the area).
Distance The distances between the circles. For the center circle, it is the distance between the center and the circle. If only one number is specified,
distance_growth determines the increment at which the distances grow for the outer circles.
The rate at which the distances between the circles grow. Only applicable when
distance is one number and
n_circles > 1. See also
