Gnuplot is a portable command-line-driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms.
Gnuplot was created to allow scientists and students to visualize mathematical functions and data interactively, but it has grown to support many non-interactive uses, such as web scripting.
Third-party applications like Octave also use Gnuplot as a plotting engine. Gnuplot has been supported and actively developed since 1986.
