The significance of data visualization in technology lies in its ability to present complex data in a digestible format. Visual representations, such as charts, graphs, and dashboards, allow stakeholders to quickly grasp insights and trends. Effective data visualization enhances decision-making by making data more accessible and understandable, enabling businesses to communicate findings clearly. By transforming raw data into visual formats, organizations can identify patterns, correlations, and anomalies, driving informed strategies and actions.
