Which feature in Excel allows you to visually represent data trends over time?

The feature in Excel that allows you to visually represent data trends over time is a chart. Charts enable users to plot data points against time, making it easier to identify patterns, trends, and changes over a specified period. For instance, a line chart is particularly effective for displaying trends because it connects data points with a continuous line, allowing viewers to quickly discern how values change over time.

In contrast, while tables organize data neatly, they do not provide the visual representation needed to quickly grasp trends. Pivot tables, on the other hand, are powerful tools for data analysis and summarization but are not designed for visual representation. Lastly, data filters help in narrowing down the data set for analysis but again do not visually depict trends; they simply allow users to view specific data points based on criteria. Thus, using a chart is the best method for visualizing data trends over time.
