What does the term 'data visualization' primarily refer to?

Data visualization primarily refers to the creation of visual graphs and charts to represent data. This process involves translating complex data sets into visual formats, such as graphs, charts, maps, and dashboards, which makes it easier for analysts, stakeholders, and decision-makers to understand trends, patterns, and insights within the data. By providing a visual representation, data visualization helps to convey information clearly and effectively, allowing for quicker interpretation and better communication of data-driven insights.

Visualizations can highlight areas of interest, clarify relationships, and reveal insights that might not be immediately apparent through raw data alone. This capability is essential in fields like data analytics, where making informed decisions based on data is crucial.
