What is the purpose of data visualization?

The purpose of data visualization is to represent data graphically and uncover insights. This involves translating complex data sets into visual formats, such as charts, graphs, and maps, making it easier for stakeholders to understand patterns, trends, and correlations. By presenting data visually, it enhances comprehension and allows for quicker decision-making as individuals can readily grasp key information without wading through large volumes of raw data.

Visualizations facilitate the identification of outliers, comparisons across categories, and changes over time, which can often be difficult to discern in numerical data alone. This means that data visualization is crucial for effective communication and interpretation of data findings, leading to informed decision-making processes based on the insights derived from the visual representations.
