From: Assembly along lines in boundary-driven dynamical system

Followers of each attractor (towards which they move), are represented by points of the same type and same color. With this convention the system splits into the slices of different colors where each slice corresponds to a different attractor. In the right panel we show two neighboring slices and their corresponding attractors. The boundary between two slices defines a line that lies on the perpendicular bisector of two neighboring attractors.
