2D Apollonian gasket with four identical circles

Plot a 2D apollonian gasket with 4 identical circles

In mathematics, an Apollonian gasket or Apollonian net is a fractal generated from three circles, any two of which are tangent to one another
The method used to create the Apollonian gasket is based on circle inversion, which is a geometrical transformation acting with a reference circle that modifies points.
% In the plane, the inverse of a point P in respect to a circle of center O and radius R is a point P' such that P and P' are on the same ray going from O, and OP times OP' equals the radius squared
OP * OP' =R²
