Winplot is a general-purpose plotting utility for Microsoft Windows that can draw (and animate) curves and surfaces presented in a variety of formats.

[4] The final 2012 release of Winplot can run on Windows 95, 98, Me, 2000, XP, Vista, 7.

It also has various export options including EPS, SVG, PiCTeX, Metafile, and simple copying to the Windows clipboard.

[6] Unlike most other free plotting software[citation needed], Winplot can plot implicit functions, slope fields, and intrinsic curves, and perform several standard calculus operations on the functions, such as generating graphs of cross-sectional solids and solids of revolution, tracing trajectories on slope fields given an initial point, and calculating line and surface integrals.
