Classification chart

Classification chart is a synopsis of the classification scheme,[1] designed to illustrate the structure of any particular field.
According to Brinton "in a classification chart the facts, data etc. are arranged so that the place of each in relation to all others in readily seen. Quantities need not be given, although a quantitative analysis adds to the value of a classification chart."[2] Classification charts show qualitative information.
Early examples of classification chart are the illustrations of the Carl Linnaeus' 1735 classification of animals and his classification of plants in his Classes Plantarum 1738. In 1752 Jean le Rond d'Alembert and Denis Diderot produced a figurative system of human knowledge produced for the Encyclopédie.
In his 1939 Graphic presentation. (first edition 1919) Willard Cope Brinton was one of the first to devoted a whole chapter on classification charts.[2]
