Universal Properties
However, even if many diagrams rely on expert knowledge, diagrams have many universal properties:
- Adults from all cultures show quantity increasing from bottom to top of a page.
- Time direction is always from left to right.
- Everybody can be aware that an object is related to another object just by observing at the connectivity between the two; it doesn’t matter what kind of connection it is as long as the connection is described as a kind of a line.
- Any more universal properties?
