The Visual Analysis of Data, and Current Research into the Stimuli Controlling It
Barry S. Parsonson, Donald M. Baer · 2015
Visual analysis is one of the oldest forms of data analysis. It is, in essence, simply the array of one set of information relative to one or more other sets of information, so that a viewer can draw a reasonable conclusion or make a reasonable hypothesis about any relationships or lack of them among these sets. Very often, the array takes the form called a graph, especially when at least one set of the information is quantitative; in other cases, especially when all the sets are qualitative, it takes the form of essentially a picture or diagram (cf. especially Tufte, 1990).
