Pegasus is a graph which offers substantially increased connectivity between the qubits of quantum annealing hardware compared to Chimera. It first fundamental change in annealers built by D-Wave since Chimera was introduced 2009 and then used 2011 for D-Wave's commercial annealer. In this article we describe an algorithm defines provide what believe be best way graphically visualize order see couple each other. As supplemental material, wide variety different visualizations expose properties ways. We open source code generating many depictions that show.
