Which statement reflects the efficiency principle in visualization?

• A. Complex models.
• B. High processing time.
• C. Quick to understand.
• D. Minimal data.

Answer: (C)

Efficiency in visualization means making the message quick and easy to grasp with minimal mental effort. A visualization that is quick to understand achieves this by clear encoding, appropriate detail, and avoiding unnecessary clutter. This is why the statement about being quick to understand best reflects the efficiency principle: it directly emphasizes speed and clarity in extracting the main insight, which supports faster and more confident decision making. The other ideas don’t fit as well because a complex model adds complexity that slows interpretation, long processing time signals more effort required to read the visualization, and using minimal data can undermine the completeness of the message and introduce ambiguity.
