An approach to data graphics design promoted by Edward Tufte.
Edward Tufte is an influential author of books on the visual display of information. He has introduced a number of distinctively minimal styles of classic statistical graphics. His graphics attempt to maximize proportion of ink (or pixels) that is used to present data compared to the total amount of ink (or pixels) present in the graphic.
