According to Abbreviation Finder, DIAG stands for diagram. The first step that we are going to make known is the etymological origin of the term diagram that now concerns us. In this case, we can state that it is a word that derives from Greek as it is made up of various components of that language:
-The prefix “dia-”, which means “through”.
-The verb “graphein”, which is synonymous with “write”.
-The suffix “-ma”, which is used to indicate “result of the action”.
Starting from that origin we can establish, therefore, that diagram literally means “sketch”.
A diagram is called a graph that reflects the relationships between the various components of a set or system.
Diagram concept
A diagram is a graphic that presents the links between the different components of a system or an assembly. It can be a drawing dedicated to the representation of something, to the resolution of a problem or to the demonstration of a proposition.
For example: “In this diagram you can see how we plan to develop the product distribution chain”, “I already showed the diagram to my boss, he was satisfied and asked me to move forward with the project”, “The government presented a new diagram of activities in the city squares”.
Classification according to type
The word diagram comes directly from the late Latin term diagramma, itself derived from the Greek language, as we have already indicated. Depending on their characteristics, it is possible to differentiate between different types of diagrams.
The representation of a process or an algorithm is called a flowchart . Many times it shows a sequence of steps to follow, with arrows linking the different stages. A block diagram, meanwhile, uses blocks to represent the inner workings of some kind of organization or system.
John Venn devised one of the best known mathematical diagrams.
Mathematical diagrams
Mathematical diagrams, on the other hand, are graphs that allow mathematical relationships to be specified. One of the best known is the Venn diagram, created by the Englishman John Venn at the end of the 19th century to show, by means of closed lines, sets of elements.
In the same way, we cannot forget the Bode diagram, which is the graphic representation whose mission is to show or characterize the frequency response of a specific system. Its name comes from the scientist who created it, the American Hendrik Wade Bode.
Another diagram is the Pareto chart, a drawing that makes it possible to order data in descending order, from left to right. This diagram is used to graph the Pareto principle, postulated by the Italian Vilfredo Pareto.
Spanish foundation
Nor can we overlook the existence of the Fundación Diagrama, which is based in Murcia (Spain) and is part of the psychosocial intervention sector. It is non-profit, it was launched in the 1990s and its objective is none other than to be able to serve people in social difficulty or who are vulnerable in favor of the defense of Human Rights.
Precisely for all this, said foundation has several areas where they carry out actions and projects of various kinds. Among those are the socio-health area, cooperation for development, socio-educational area, socio-labour insertion, communication and awareness.
