Main diagram types

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:See
  • 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:
  • histogram, bar chart
  • pie chart
  • function graph
  • scatter plot
  • table / matrix

• Other types of diagrams, e.g.
  • exploded view
