Data visualization tools assist in understanding complex datasets by transforming raw data into informative visual representations, such as graphs or dashboards. These tools help to unveil trends, patterns, and correlations that might not be apparent in text-based data. By providing an intuitive interface, they enable users, including non-technical stakeholders, to interpret data effectively and make informed decisions. Furthermore, interactive features in visualization tools allow for drill-down capabilities, enhancing user engagement and deepening insight into data-driven questions, ultimately improving the decision-making process.
