Which statement is NOT a benefit of data visualization?

• A. Accessibility in terms of visual appeal and ability to easily understand
• B. Real-time processing means the picture is always up to date
• C. Increased decision making and efficient use of resources
• D. Requires significant training to interpret visuals

Answer: (D)

The key idea is that data visualization is meant to make data easy to understand at a glance and to support quick, informed decisions. Benefits typically include making information accessible and visually engaging so people can grasp insights easily, enabling real-time updates so dashboards reflect current conditions, and improving decision making and efficient use of resources by highlighting patterns and priorities. The statement that interpreting visuals requires significant training does not fit as a benefit; good visual design aims to minimize training needs and make insights accessible to a broad audience. In practice, while some complex dashboards might require more learning, the overall purpose is to reduce the effort needed to understand the data.
