A command-driven interactive graphing program. Gnuplot can plot two-dimensional functions and data points in many different styles (points, lines, error bars); and three-dimensional data points and surfaces in many different styles (contour plot, mesh). It supports complex arithmetic and user-defined functions and can label title, axes, and data points. It can output to several different graphics file formats and devices. Command line editing and history are supported and there is extensive on-line help.

Gnuplot is copyrighted, but freely distributable. It was written by Thomas Williams, Colin Kelley, Russell Lang, Dave Kotz, John Campbell, Gershon Elber, Alexander Woo and many others. Despite its name, gnuplot is not related to the GNU project or the FSF in any but the most peripheral sense. It was designed completely independently and is not covered by the General Public License. However, the FSF has decided to distribute gnuplot as part of the GNU system, because it is useful, redistributable software.

Gnuplot is available for: Unix (X11 and NEXTSTEP), VAX/VMS, OS/2, MS-DOS, Amiga, MS-Windows, OS-9/68k, Atari ST and Macintosh.

The figure(s) can be uploaded files (png, gif or jpeg) or they can be rendered from a text based image format (R-image (R Development Core Team, 2011) or Gnuplot (Williams and Kelley, 2010)).
The examples and exercises are implemented in C programming language, but the tools used, such as Gnu Scientific Library and GnuPlot are at the heart of the book, and specific algorithms and calculations rely on them almost exclusively.
Por ejemplo, Maxima, Reduce y Xcas pueden efectuar calculo simbolico y numerico; Scilab y Octave pueden realizar calculo numerico; Geogebra sirve para explorar objetos geometricos; Lyx, para escribir trabajos cientificos; el compilador gcc funciona para compilar programas en C y en Fortran; Python, Lua y Ruby, para escribir programas en lenguaje de scripts; gnuplot, puede realizar graficos para las ciencias y la ingenieria.
