Tooltips

Definition

Tooltips are small informational boxes that appear when a user hovers over or clicks on an element in a data visualization. They provide context-sensitive information, allowing users to quickly understand data points without cluttering the overall visualization. This feature enhances interactivity, helping users engage more effectively with the data presented.

5 Must Know Facts For Your Next Test

1. Tooltips can display various types of information, such as numerical values, descriptions, or images related to the data point being hovered over.
