Data visualization tools typically employ technologies like interactive dashboards and big data analytics to deliver insights from complex datasets. These tools use visual elements such as charts, graphs, and maps to represent data in an easily understandable format, facilitating better decision-making. By transforming raw data into visual context, businesses can quickly identify trends, correlations, and outliers, thus supporting data-driven strategies. Technologies like machine learning and data mining further enhance these tools by enabling more sophisticated analyses and predictions.
