In computing, visual programming is a type of programming that lets humans describes processes using illustrations. While a typical text based programming makes programmer thinks like a computer, a VPL lets the programmer describe the processes in terms that makes sense to humans. In other words, it is a programming language where a program is represented and manipulated graphically rather than as text. Examples of visual programming languages include Gamemaker, Kodu, Lego Mindstorms, MIT and so on. It allows you to manipulate visual elements to make a program. For example, drag and drop blocks. It enables the development of software programs by eliminating textual software with a series of visual graphics elements. VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols used either as elements of syntax or secondary notation. The structural units of VPL include line, shape, colour, form, motion, texture and so on. Visual programming language is further detailed in the presentation.
