Answer 5

Visualization tools should be used when the data being presented could benefit from structure, style, symbolism, or summary.

1. Structure – any time concepts or information fit into groups or have a relationship with one another, it is helpful to display this relationship graphically.
2. Style – the style of presentation that exists as a cultural norm in a particular organization.
3. Symbolism – If there is a symbol that the audience recognizes that can take the place of a bunch of words, using it will probably lead to quicker understanding.
