gnuplot: Powerful and feature rich application for 2D and 3D rendering.

Gnuplot is an open-source, software that was specifically designed for scientists, students, and researchers, and will allow them to plot and visualize data sets in an interactive manner.

It also comes with a well-organized interface that gathers its feature set inside a few menus that are robust, while each menu is dedicated to achieving a major task like options related to expressions, including operators, which are encased in a single menu.

The program throughout its development time has become an extensive platform that can be used for a wide array of purposes, which also includes web scripting, while its plotting engine has been adopted by many third-party applications, like Maxima, Gretl, and Octave.

It will allow users to generate both 2D and 3D plots and deliver the results on the screen in animated views, and even save the graphs to a variety of image formats, like PNG, SVG, JPEG, and EPS.

The program is also related to LaTEX code and can manipulate its engine even inside LaTEX documents, while also supporting batch scripts, for better automation in various systems.

Gnuplot is a powerful and feature-rich application that is capable of 2D and 3D rendering, and also includes a collection of demo files which is very useful for beginners.
