What is data visualization?

• A. The graphical representation of data to identify patterns, trends, and insights.
• B. A method of cataloging books.
• C. A type of ready reference.
• D. A conversation between librarian and user.

Answer: (A)

Data visualization is the graphical representation of data to reveal patterns, trends, and insights. By turning numbers into charts, graphs, maps, and dashboards, you can quickly see how values compare, how they change over time, and how different variables relate. In libraries, this helps you understand usage patterns, such as which genres circulate most during certain months or how wait times vary by format, making decisions about collections and services more evidence-based. The other options describe tasks like cataloging, quick-reference resources, or conversations with users, which are important library activities but not what data visualization is.
