What method is typically used to enable visual comparison of incidents over time?

Line charts are particularly effective for enabling visual comparison of incidents over time due to their ability to display trends and changes. They plot data points in a chronological order and connect them with a continuous line, which helps in illustrating patterns, peaks, and valleys in the data. This temporal aspect allows users to easily observe how the number of incidents increases or decreases over specific intervals, thus giving a clear picture of trends over time.

While bar charts can also show quantities across different time frames, they do not emphasize continuous changes as effectively as line charts. Indicators provide a snapshot of current values or conditions but do not allow for an understanding of trends over time. Tables present data in a static format, which can be harder for users to interpret trends visually compared to the dynamic nature of line charts.
