Which type of graph is most commonly used to measure trends over time?

A line graph is the most commonly used type of graph to measure trends over time because it effectively displays data points at various intervals, allowing viewers to easily observe how values change over a specific period. The continuous nature of a line graph connects these points with lines, making it straightforward to identify increases, decreases, or patterns in the data over time.

For instance, when tracking sales figures or temperature changes, the line graph can reveal upward or downward trends quickly, facilitating better analysis and understanding of the data. This makes line graphs particularly useful for presentations or analyses focused on temporal data trends, distinguishing them from other graph types that may serve different purposes.
