Data visualization plays a critical role in understanding complex datasets by transforming raw data into visual formats like charts, graphs, and infographics. This process aids in revealing patterns, trends, and correlations that might be difficult to discern in numerical form. Effective visual tools allow stakeholders to comprehend complex information quickly, facilitating better decision-making. Additionally, data visualization promotes storytelling through data, making insights more accessible to non-technical audiences and enabling discussions based on clear visual representations.
