The significance of data visualization in data analysis lies in its ability to simplify complex information and make it easier to understand. By presenting data in graphical formats, such as charts and dashboards, visualization helps analysts and decision-makers identify patterns, trends, and outliers quickly. Effective data visualization enables better communication of findings, supports data-driven decision-making, and enhances storytelling with data. It transforms raw data into actionable insights, driving strategic planning and performance optimization within organizations.
