Where 3 or more states make up an attractor cycle, this is represented as a regular polygon with nodes at the vertices. The direction of time is clockwise. The ``last'' vertex is shown due east, so the first vertex at which the cycle is entered is one node clockwise from due east. A point attractor is shown as a node (positioned north-east) on a circle, indicating that the node cycles to itself. A two state attractor is shown as two nodes on a circle (positioned south-east and north-west), where the south-east node is the ``last'' node. The diameter of attractor cycles increases asymptotically with system size n, up to the maximum selected, which also determines the scale of the entire basin.
