What is data visualization?

• A. Graphical representation of data to reveal insights
• B. A method of deleting duplicate data
• C. A type of data backup
• D. A process for securing data

Answer: (A)

Data visualization is the graphical representation of data to reveal insights. It turns raw numbers and information into visuals like charts, graphs, maps, and dashboards so patterns, trends, comparisons, and outliers stand out clearly. This makes complex data easier to understand at a glance and supports quicker, more informed decision making. The other ideas describe different data-management activities. Deleting duplicate data is data cleansing or deduplication, not visualization. A data backup is about preserving data for recovery, and securing data focuses on protecting data from threats. None of those are about turning data into visuals that communicate findings.
