From: A journey from order to disorder — Atom by atom transformation from graphene to a 2D carbon glass

Analysis of the short-range disorder.
(a–c) Distribution of the inter-atomic distances (radial distribution function, g(r)) for pristine graphene, a structure at an intermediate density deficit of ca. 5.4% and at a higher density deficit of ca. 7.1%, respectively. (d) The angular distribution function (α(θ)) for the same structures. Example areas of the structures for the intermediate and high dose cases are shown in panel (e) and (f) with tetragons colored yellow, pentagons red, heptagons blue and octagons violet.
