Визуальное программирование. Visual programming language. In computing, a visual programming language (VPL) is any programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually.
A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs (known as dataflow or diagrammatic programming)[1] are based on the idea of "boxes and arrows", where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations.
Definition[edit] VPLs may be further classified, according to the type and extent of visual expression used, into icon-based languages, form-based languages, and diagram languages. Visual programming environments provide graphical or iconic elements which can be manipulated by users in an interactive way according to some specific spatial grammar for program construction. Visual language. A visual language is a system of communication using visual elements.
Speech as a means of communication cannot strictly be separated from the whole of human communicative activity that includes the visual[1] and the term 'language' in relation to vision is an extension of its use to describe the perception, comprehension and production of visible signs. Overview[edit] An image that dramatizes and communicates an idea presupposes the use of a visual language. Just as people can 'verbalize' their thinking, they can 'visualize' it.
