• Visual symbols are representation of direct
reality, which comes in the forms of signs and
symbols.

• 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
connection between the items.

summaries of our direct experiences
or our rich indirect experiences … A
little can stands for a lot !”
