[Brath, 1997]
Charts and Graphs
In The Visual Display of Graphical Information of Edward Tufte, a milestone in the theory of graph design, principles of graph design are discussed. One of them is: Try to maximise the data density. [Hunt and Mashhoudy, 2002]
While the human eye has the ability to detect large amounts of information within a very small area, statistical graphs often fail to take advantage of this ability. To messure the information content of a graph he definses the data density. [Hunt and Mashhoudy, 2002]
