What is the main goal of data visualization?

The main goal of data visualization is to convey patterns and insights from data using graphical representations. This approach allows individuals to quickly grasp complex information by representing data visually, making it easier to identify trends, correlations, and anomalies that may not be readily apparent in raw data. Effective data visualization transforms data into a more accessible format, facilitating better decision-making and communication of findings.

In contrast, the other options focus on different aspects of data management and usage. Storing data in a compressed format pertains to data storage efficiency rather than interpretation. Automating data entry processes relates to operational efficiency, while protecting data from security breaches concerns cybersecurity, which is separate from the goal of visualizing data. Therefore, the focus on graphical representation as a means to uncover insights is what positions data visualization as a critical tool in understanding and leveraging data effectively.
