Graph is described as 'Open source application used to draw mathematical graphs in a coordinate system. Anyone who wants to draw graphs of functions will find this program useful. The program makes it very easy to visualize a function and paste it into another program' and is a Calculator in the education & reference category. There are more than 50 alternatives to Graph for a variety of platforms, including Windows, Mac, Linux, Web-based and BSD apps. The best Graph alternative is R (programming language), which is both free and Open Source. Other great apps like Graph are SageMath, Matplotlib, GeoGebra and GnuPlot.
Open source framework for numerical computations and advanced statistical analysis, featuring nonlinear curve fitting, ODE solving, 1D/2D publication-quality visualization, Fourier and wavelet transforms, intuitive syntax, and namespace-based code organization for research.
GeoGebra Discovery is an experimental version of GeoGebra. It contains some bleeding edge features of GeoGebra that are under heavy development and therefore not intended for every day use yet, so they are not included in the official GeoGebra version.
