Overview

Data visualization is the graphical representation of data, helping to uncover trends, patterns, and insights quickly. It transforms complex data into intuitive visuals like charts, graphs, and dashboards, making analysis more accessible. By presenting data visually, it supports faster decision-making and storytelling with impactful insights. Effective data visualization is key for engaging audiences and enhancing data-driven strategies.
