"Data visualization" in analytics refers to the graphical representation of data to facilitate understanding and communication of insights. By using charts, graphs, and dashboards, complex data sets are simplified, allowing stakeholders to quickly identify trends, correlations, and patterns that may not be obvious in raw data. This process enhances decision-making by transforming quantitative information into a visually engaging format, thereby improving analysis and comprehension. Effective data visualization can lead to better strategic planning and operational improvements.
