What is the purpose of data visualization in informatics?

• A. To present data graphically to aid interpretation and decision-making.
• B. To store patient data securely.
• C. To encrypt communications.
• D. To align coding standards with clinical guidelines.

Answer: (A)

Data visualization in informatics is about presenting data graphically to aid interpretation and decision-making. By turning numbers into charts, graphs, and dashboards, it helps clinicians and administrators quickly see patterns, trends, and outliers, supporting faster, more informed choices. It makes complex data accessible at a glance and facilitates monitoring of metrics, comparisons over time or groups, and clear communication of findings to stakeholders. While securing data and aligning standards are important, visualization specifically focuses on conveying insights visually rather than handling security or governance tasks.
