Diagram
From Wikipedia, the free encyclopedia
(Redirected from Diagrams)
A diagram is a 2D symbolic representation of information according to some visualization technique. Sometimes, the technique uses a 3D visualization which is then projected onto the 2D surface.
The word graph is often used as a synonym for diagram.
There are at least the following types of diagrams:
- Graph-based diagrams: these take a collection of items and relationships between them, and express them by giving each item a 2D position, while the relationships are expressed as connections between the items or overlaps between the items; examples of such techniques:
- tree diagram
- network diagram
- flowchart
- Euler diagram, Venn diagram, existential graph
- Maps (when stylized, e.g. the map of the London underground)
- Chart-like diagram techniques, which display a relationship between two variables that take either discrete or a continuous ranges of values; examples:
- Other types of diagrams, e.g.
Thousands of diagram techniques exist. Some more examples follow.
