“A diagram is a symbolic representation of information according to some visualization technique.” [Diagram. Wikipedia]

Specific meaning of the term diagram is 2D visualization of qualitative information, consisting of visually linked simplified figures.

Often these simplified figures are geometric shapes. Some diagrams use flat projections of 3D objects as design elements.

These shapes often, but not always, are connected with lines or arrows.

In many types of diagrams shapes and connection lines are used according fo the set of rules specified by standard notation.

Different types of diagrams can visualize interconnections and logical relations of elements, structures of complex systems and process flows.

Diagrams contrast with charts and graphs wich both visualize quantitative data.

Usually diagrams are abstract illustrations with descriptions integrated in context of text documents. Therefore diagrams contrast with infographics which are self-sustained graphics rich one-page stories.

In contrast with maps and plans, diagrams are not represent spatial information.

Diagrams usually consist of abstract shapes and symbols, not literal item images in contrast with technical drawings and sketches.

The diagram is elegant mean to simplify complexity. Diagramming is very effective way of graphic communication, fast explanation of difficult subjects, and visual learning.

You can use diagrams to illustrate your documents, presentation slides or web site. Properly used diagrams help you to explain your idea clearly and quickly. Diagrams help you to present your message to target audience, and produce the desired impression and conclusions.

• Block diagram
• Bubble diagram
• Circle-spoke diagram
• Circular arrows diagram
• Concept map
