* **Linking** is when data points are connected. In the context of brushing, this allows a user to explore high dimensional spaces by selecting collections of points in one dimension and determining where they lie in another dimension.   * **Staging** is a storytelling tool, allowing the author to reveal or highlight parts of a figure in sequence. The highlighting can take the form of Brushing and Linking as above. The example below shows a five-stage figure, where each panel is interactive, and offers a different view of the same data (see caption).
