Trend Line

The "Trend Line" tag is applied to images that feature a line or curve superimposed on a chart, typically a line graph or scatter plot, to illustrate the general direction or pattern of data over time or between variables. These lines help visualize long-term movements, correlations, or underlying relationships within complex datasets, making them easier to interpret. They are useful for highlighting trends in statistics, economics, social sciences, and environmental data.
