Graphicacy is defined as the ability to understand and present information in the form of sketches, photographs, diagrams, maps, plans, charts, graphs and other non-textual formats.
Origin
The word graphicacy was coined in 1965 by geographers
William Balchin and
Alice Coleman as a characterisation of visuo-spatial and cartographic abilities, "the communication of spatial information that cannot be conveyed adequately by verbal or numerical means", including the whole field of graphic arts and much of geography, cartography, computer-graphics, and photography. The word "graphicacy" was chosen by analogy with
literacy
Literacy is the ability to read and write, while illiteracy refers to an inability to read and write. Some researchers suggest that the study of "literacy" as a concept can be divided into two periods: the period before 1950, when literacy was ...

Differences from other skills
Interpretation of graphics is loosely analogous to the process of
reading text
Text may refer to:
Written word
* Text (literary theory)
In literary theory, a text is any object that can be "read", whether this object is a work of literature, a street sign, an arrangement of buildings on a city block, or styles of clothi ...

s) are expected to be organised according to broad conventions (such as being sequenced in orderly rows starting from top left and progressing down the page). However graphics are not subject to a similarly stringent set of structural conventions. Instead, it is the content itself that determines the nature of the graphic entities and the way they are arranged. For example, the
form and spatial arrangement of the items that comprise the actual subject matter being represented in the graphic are used as the basis for the graphic entities and structure that are displayed in the graphic. This is not the case with written text where the words and their arrangement bear no resemblance to the represented subject matter.
Because of these and other fundamental differences between text and graphics, the processes involved in
comprehension and production of graphics are distinguished from those involved in comprehension and production of text.
Issues
The concept of graphicacy acknowledges the characteristic features of graphic information that distinguish it from other forms of representation such as
verbal and numerical information. Separating graphicacy from

delineates the distinctive and complementary types of contributions that graphics, words, and numbers each make in human communication.
The interpretative components of graphicacy skills are relevant in the increasing range of situations where graphics carry the primary responsibility for communication. Early recognition of the importance of graphicacy came from disciplines such as geography, science and mathematics in which graphics play a key role. Educators in these and similar disciplines have become increasingly concerned with the capacities of students to comprehend information presented by way of graphics.
The interpretation of certain types of graphics can sometimes be very challenging. In addition, it is thought that graphicacy skills are largely learned rather than innate and that a viewer's capacity to interpret particular types of graphics is related to their background knowledge, in particular knowledge about the specific ''graphic system'' used to depict the subject matter, and knowledge about the ''subject matter'' that is depicted in the graphic. Severe deficiencies in either of these aspects of background knowledge may prevent a viewer from comprehending a graphic.
Example
There are some fundamental differences between written text and a graphic representation. For example, a brief explanation of the structure of a bowstring arch bridge may read:
''Spanning the river is the bridge’s arch structure with its ends carried by abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end that provide vertical and lateral support for the span, as well as acting as retaining walls ...
s on each bank. The deck of the bridge is suspended by struts attached to the arch and runs between the banks. Each end of the deck is connected to the arch's legs.''
The main items mentioned, extracted and arranged in their order of mention in the text, would read:
''River; Bridge; Arch; Ends of arch; Abutments; Banks; Deck; Bridge; Struts; Arch; Banks; Ends of deck; Arch legs''
The signs used to represent parts of the bridge in words are very different from the signs used in the picture of the bridge. Furthermore, the same items (such as bridge, arch, and banks) are often mentioned more than once in the text version, due to the constraints of text as a representational system. However, in a graphic of this bridge, such information would only need to appear once. The arrangement of these items is also different in the text from what it would be in a graphic. When compared with the order of mention in the text with this depiction, the text is not arranged in a way that would directly map onto the bridge, but presents the bridge's components in a linear sequence that gives no visual indication of the bridge's structure.
