The main goal of data visualization is to present complex data in an understandable and visually appealing manner. By transforming data into graphical formats, such as charts, graphs, and maps, users can easily identify trends, patterns, and outliers that may not be evident in raw data. Effective data visualization aids in decision-making by enabling stakeholders to grasp insights quickly and intuitively. Additionally, it fosters better communication of information among teams and clients, making data-driven discussions more accessible. Ultimately, data visualization enhances the overall understanding of data and drives informed strategies.
