Data visualization

Definition

Data visualization is the graphical representation of information and data, utilizing visual elements like charts, graphs, and maps to communicate complex data insights clearly and effectively. By transforming raw data into a visual context, it helps individuals understand patterns, trends, and correlations that might go unnoticed in text-based data. This technique is crucial for making informed decisions based on public records, analyzing documents, and interpreting analytics and metrics.
