There are at least the following types of diagrams:

===Logical===
* [[Logic]]al or conceptual diagrams, which 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, for example:

===Quantitative===
* Quantitative diagrams, which display a relationship between two variables that take either [[Discrete mathematics|discrete]] or a [[continuous function|continuous]] range of values; for example:

===Schematic===
* [[Schematic]]s and other types of diagrams, for example:

Many of these types of diagrams are commonly generated using diagramming software such as [[Microsoft Visio|Visio]] and [[Gliffy]].

Diagrams may also be classified according to use or purpose, for example, explanatory and/or [[How To (disambiguation)|how to]] diagrams.

Thousands of diagram techniques exist. Some more examples follow:
