Which feature allows users to see how data changes over time?

The Pages shelf is specifically designed to help users visualize data changes over time by allowing them to create time-based animations. When a field is placed on the Pages shelf, Tableau generates a separate view for each unique value of that field, which is particularly useful for date or time dimensions. As users interact with the Pages shelf, they can navigate through the timeline, effectively "paging" through the data to see how metrics evolve across different periods. This dynamic capability makes it easier to identify trends or patterns over time within the dataset.

In contrast, the other options serve different functions. The Filters pane is used to narrow down the data being displayed, the Columns shelf is intended for defining the structure of the view by placing dimensions or measures for horizontal display, and the Marks card is used to modify the presentation of data points, including aspects like color, size, and shape. While each of these components enhances data visualization, they do not specifically facilitate the examination of time-based changes like the Pages shelf does.
