A Theory of Graphs for Reading Comprehension and Writing Communication.
Fry, Edward
Graphs are increasingly being used in written communication and writers expect readers to understand them. One definition of graphs--information transmitted by position of point, line or area on a two dimensional surface--excludes displays composed chiefly of numbers or words such as tables or outlines. However, it does include time lines, flow charts, curve (line) graphs, bar graphs, scattergrams, pie graphs, dials, maps, pictures, and abstract drawings because they all transmit information nonsymbolically on a two dimensional surface. Fundamental to comprehending (reading) or writing a graph is knowing the types of underlying coordinates, the scaling, and other factors. The underlying theory is that all graphs are basically one dimensional, two dimensional, or three dimensional. A taxonomy of graphs can help elucidate this theory with numerous categories and examples. Together, the definition, theory, and taxonomy can be useful for teaching and testing graph knowledge in the public schools and in helping writers and readers in many communication media, including journals, textbooks, popular press, computer graphics, and television. (Appended is a taxonomy of graphs.) (Author/HOD)
