Diagrams such as flowcharts can be very helpful in showing the relationship between different issues, organisations, ideas or processes. They are often used as decision-making tools. However, if you try to include too many elements or steps, the diagram will become cluttered and hard to read, and lose its purpose.

Keep the relationships between elements of the diagram simple and intuitive. The meaning of arrows between elements or steps should be clear.

Infographics can become ineffective and distracting if they are overloaded with graphical elements. There are many examples of infographics that display data inaccurately and incoherently.
