Visualization

Definition

Visualization refers to the graphical representation of data and results, allowing complex information to be presented in a clear and comprehensible way. This process helps in interpreting data by transforming raw numbers and statistics into visual formats such as charts, graphs, and images, which aids in identifying patterns, trends, and anomalies that may not be apparent from the raw data alone.
