Which chart type may be employed to analyze trending data over time?

The timeline chart is specifically designed to visualize data points in relation to time, making it an excellent choice for analyzing trends over a period. This type of chart allows users to observe changes and patterns as they relate to time intervals, enabling better insights into temporal dynamics.

For instance, a timeline chart can provide a clear view of how sales figures, user engagement, or other metrics fluctuate across days, months, or years. It effectively highlights trends, cycles, or even seasonal variations, making it much easier to draw conclusions about how a variable behaves over time.

In contrast, other chart types serve different purposes. Bar charts can compare discrete categories, bubble charts can show the relationship between three numeric values, typically involving sizes and positions, and heat maps represent data density and correlations but are less effective at depicting trends over time.
