GraphCalc is an open source computer program that runs in Microsoft Windows and Linux that provides the functionality of a graphing calculator. GraphCalc includes many of the standard features of graphing calculators, but also includes some higher-end features: GraphCalc was developed by Brendan Fields and Mike Arrison, computer science students at Bucknell University, before graduating in 2000. Mike continued the development briefly from 2001–2003, but has since abandoned the project. Other similar projects being maintained are KAlgebra and Cantor.
