Graphical user interface

Definition

A graphical user interface (GUI) is a visual way for users to interact with computers and software using graphical elements like windows, icons, buttons, and menus. GUIs make it easier for users to understand and navigate complex software applications by allowing them to engage with visual representations instead of relying solely on text commands. This enhanced interaction is particularly crucial in simulation tools, where users can manipulate various parameters and visualize results in real time.
