Speaking of Graphics

An Essay on Graphicacy in Science, Technology and Business

by Paul J. Lewi, PhD, Eng, Consultant (1937-2012)

Graphics can be defined as translations of numbers in the form of a drawing, design or plan to explain or illustrate something. For our purpose, however, this definition is at the same time too broad and too narrow. In this essay we only consider graphics that are derived from tabulated observations or measurements. On the one hand, we omit technical, organizational and architectural drawings and graphics representing mathematical functions. On the other hand, we also extend the scope of graphics from explanation and illustration of known facts and relationships to the exploration and search for relevant questions and working hypotheses.
