Harvard Graphics, from Software Publishing Corporation and initially called Harvard Presentation Graphics, is a graphing/plotting/presentation creation application for DOS. It was extremely popular in the late 1980s. At release, it competed against many graphing products such as PFS:Graph (AKA IBM Graphing Assistant ), Microsoft Chart, ChartMaster, and Cricket Graph, just to name a small few. A Windows port was released in 1991, but it lost out to Microsoft Powerpoint.
