What is data visualization?

Data visualization refers to the graphical representation of information and data, making complex data more accessible and understandable through visual formats such as charts, graphs, and maps. This technique helps identify patterns, trends, and correlations that might not be immediately apparent in raw data. By leveraging visual elements, data visualization simplifies the presentation of data, allowing users to interpret information more effectively and make data-driven decisions.

The other options do not accurately define data visualization. Storing data securely pertains to data management and security practices rather than visual representation. While software tools for data analysis may incorporate data visualization features, they are not synonymous with the concept itself. Similarly, encoding data refers to the process of converting data into a specific format for storage or transmission, which also does not relate directly to visual representation.
