Abstract
This paper is a critique of current approaches to the development of computer graphing and graph visualization programs. Developers of these programs model the user as an individual problem solver who is reliant on perceptual skills to create and interpret graphed information. Such a model of graphing is ill-suited to meet the complex needs of real users, a supposition that is supported by work in two major areas of graphing theory and research: the sociology of science and the educational research of mathematics and scientific students. These areas have not been traditionally cited when planning computer graphing or visualization programs or when assessing their usability. A review of the literature in these fields reveals that an over-reliance on a user's perceptual skills is unlikely to result in successful graph practices.
