What does visualization mean?
Visualization is the process of making something visible, either by creating a mental image in the mind or by expressing information through pictures, diagrams, charts, maps, or animations. Its best-known modern use is in data visualization, where numerical information is transformed into a form that reveals relationships, trends, and exceptions more readily than a table alone. The word also has a psychological sense: a person may speak of visualizing a place, event, or desired future in vivid detail. In this context, visualization is associated with imagination, rehearsal, and focused attention, although it does not guarantee that what is imagined will occur. In technical communication, a visualization is valued for clarity and accessibility, but it may also simplify or distort the information it represents. The term is used in both British and American English, with the spelling differing between the two varieties.
