Which of the following best describes how to annotate visualization for quick interpretation?

• A. Hide data points
• B. Replace axis labels
• C. Highlight key findings for quick interpretation
• D. Make the chart look busy

Answer: (C)

Highlighting key findings for quick interpretation guides the viewer to the most important message right away. Annotations should draw attention to clear patterns, comparisons, or standout values with concise labels or callouts so someone can understand the takeaway without scrutinizing every data point. This keeps the visualization informative and easy to scan, while preserving the data’s integrity because the underlying points remain visible. Hiding data points removes context and potentially relevant information; replacing axis labels can mislead or confuse how the data are read; and making the chart look busy adds clutter that hinders quick understanding.
