Tufte Principles Name: Professor: Institution: Course: Date: Abstract In Tufte’s principles, the visual representations of data must tell the truth. He shows a range of graphs that either under or over represent the effects of data to a reader. The six principles of graphical integrity include the representation of numbers, should be proportional to the numerical quantities represented, detailed, clear and thorough labeling to be used so as to avoid the graphical ambiguity and distortion (Tufte 2001)…
The above describe the data integrity. In addition, Tufte also touched on data ink, whereby he claims that a clear graphical representation maximizes data ink and removes as much non-data ink as possible. He put five principles of relating to data ink, which include, show data above all else, erase non-data-ink, remove redundant data ink, maximize the data ink ratio and finally revise and edit. The unnecessary and an excessive use of effects of graphics is called chart junk, which, is one of the principals that he talks explains. He states that the worst graph is self promoting and is used to demonstrate the ability of the designer, instead of displaying the data. The density of data of a graph is the total size of the graph, which shows the data. He insists that data density and matrix should be maximized within reason (Few 2009). An example of achieving this effect is through the shrink principle, which states that most graphs can be reduced without losing the legibility of the information. Another principle of his is the small multiples whereby it is a series of small graphs that have been repeated in one visual. ...
