What is annotation and commentary in visuals?

< 1 min read

Annotation and commentary add explanatory notes directly to visuals.
They highlight important events, changes, or business context.
For example, marking a revenue drop due to a policy change.
In one project, I added annotations to show when a price revision was implemented.
This helped management understand the impact on sales trend.
Commentary can be text boxes or dynamic insights.
They improve data storytelling and reduce misinterpretation.
Annotations connect numbers with real business events.
