Diagrammatic reasoning

Diagrammatic reasoning is reasoning by means of visual representations. The study of diagrammatic reasoning is about the understanding of concepts and ideas, visualized with the use of diagrams and imagery instead of by linguistic or algebraic means.

A diagram is a 2D geometric symbolic representation of information according to some visualization technique. Sometimes, the technique uses a 3D visualization which is then projected onto the 2D surface. The term diagram in common sense can have two meanings. In science the term is used in both ways. For example, Anderson (1997) stated more general 'diagrams are pictorial, yet abstract, representations of information, and maps, line graphs, bar charts, engineering blueprints, and architects' sketches are all examples of diagrams, whereas photographs and video are not'. On the other hand, Lowe (1993) defined diagrams as specifically 'abstract graphic portrayals of the subject matter they represent'. In the specific sense diagrams and charts contrast computer graphics, technical illustrations, infographics, maps, and technical drawings, by showing 'abstract rather than literal representations of information'. The essences of a diagram can be seen as: Or as Bert S. Hall wrote, 'diagrams are simplified figures, caricatures in a way, intended to convey essential meaning'. According to Jan V. White (1984) 'the characteristics of a good diagram are elegance, clarity, ease, pattern, simplicity, and validity'. Elegance for White means that what you are seeing in the diagram is 'the simplest and most fitting solution to a problem'. A logical graph is a special type of graph-theoretic structure in any one of several systems of graphical syntax that Charles Sanders Peirce developed for logic. In his papers on qualitative logic, entitative graphs, and existential graphs, Peirce developed several versions of a graphical formalism, or a graph-theoretic formal language, designed to be interpreted for logic.
