Data visualization

Definition

Data visualization is the graphical representation of information and data, using visual elements like charts, graphs, and maps to help communicate complex data sets clearly and effectively. This approach not only aids in identifying patterns and trends but also enhances understanding and decision-making in fields such as public health by making data more accessible and interpretable.
