Specific diagram types
 See also: General diagram types
A diagram type is a diagram with a specific shape and methodology, relatively independent of any field of application. Now there is no general accepted classification of diagrams. This gallery only gives an impression of the types of diagrams in the Commons at present.
General diagram types[edit]
General diagram types are diagrams with specific shapes and methodology present with multiple specific types in multiple fields of application. There are two kinds of general types here:
General diagram shapes[edit]
Basic or general diagrams shapes here are diagrams with a typical basic shape.

Onion diagrams

Venn diagrams
General concept diagrams[edit]
Basic or general diagrams with a typical basic concept, present in multiple fields of application.
