Jmol provides a proof-of-concept for CLEG as well as a first implementation. All of the calculations and figures in this paper were generated using Jmol. Structures were either generated de novo using Jmol's MODELKIT command or loaded from the AFLOW Encyclopedia of Crystallographic Prototypes . All of the images (see supporting information) can be dragged back into Jmol to recreate the indicated interactive 3D model. In this section, the way CLEG is implemented in Jmol is discussed.
