"the repertoire of colored sensations which can be produced at equal value."

“When the correspondences on the plane can be established among all the divisions of the same component, the construction is a network.”

“To analyse graphic representation precisely, it is helpful to distinguish it from musical, verbal and mathematical notations, all of which are perceived in a linear or temporal sequence. The graphic image also differs from figurative representation essentially polysemic, and from the animated image, governed by the laws of cinematographic time. Within the boundaries of graphics fall the fields of networks, diagrams and maps. The domain of graphic imagery ranges from the depiction of atomic structures to the representation of galaxies and extends into the spheres of topography and cartography.”

“When the correspondences on the plane can be established between:”

“As with any graphic, networks are used in order to discover pertinent troups of to inform others of the groups and structures discovered. It is a good means of displaying structures, However, it ceases to be a means of discovery when the elements are numerous. The figure rapidly becomes complex, illegible and untransformable.”

“Information is the reply to a question.”

“A graphic is a diagram when correspondences on the plane can be established among all elements of another component.”
