Medical Data Visualization refers to the graphical representation of health-related data to enhance understanding and decision-making. It involves using charts, graphs, and maps to display complex information, such as patient statistics, treatment outcomes, and disease trends, making it easier for healthcare professionals to interpret and analyze. This technique is crucial in public health, clinical research, and patient care, as it helps identify patterns and correlations in data. By transforming raw numbers into visual formats, Medical Data Visualization aids in communicating findings effectively, ultimately improving patient outcomes and supporting evidence-based practices in the medical field.
