Data envelopment analysis (DEA) is a useful technique for assessing the relative efficiency of a set of decision-making units. Although widely known and used by practitioners, its presentation in the managerial community is difficult without suitable visualization techniques. This article examines various two-dimensional charts for illustrating the DEA efficiency results. The presented charts have been drawn using an experimental DEA software tool, AskDEA, developed by the authors.
