Which report feature can help visualize trends over time using survey data?

The feature that specifically helps visualize trends over time using survey data is Trend Analysis. This type of analysis is designed to track changes in responses across multiple survey waves or over specified periods. It allows users to observe how responses vary, identify patterns, and make data-driven decisions based on the trends uncovered.

Trend Analysis is particularly effective for measuring progress, understanding the impact of changes, and predicting future behaviors or responses based on historical data. By visualizing this information over time, users can gain insights into the dynamics of their respondents' attitudes or behaviors, which is essential for effective decision-making.

The other options, while useful for data representation in their own ways, do not specifically facilitate the visualization of trends over time as effectively as Trend Analysis does. For example, a Dashboard Report is more about aggregating various data points into one view, and a Cloud Chart displays data in a visually engaging way but does not inherently show trends over time. Column Analysis primarily focuses on comparing categorical data rather than capturing temporal changes.
