The ConstructRing macro is used to create each of the magenta rings seen in Sections 2.1 and 2.2. This allows many rings to be added without unnecessarily complicating the network. It works by first using the Construct module to create a 1-D data field with 100 data points, coordinates
(where 
is an input of the macro),
, and data values all 0. This field is then scaled
using ScalePositions2D macro and converted to Cartesian coordinates
using the PolarTransform macro. Finally, the ShowConnections
module is used to convert this field into a visible ring.
