What type of chart is specifically designed to display changes in data over time?

A line chart is specifically designed to display changes in data over time, making it the ideal choice for tracking trends and patterns across a continuous time scale. The primary characteristic of a line chart is that it connects individual data points with lines, allowing viewers to easily visualize how values shift over time. This makes it particularly useful for analyzing time series data, such as stock prices, sales figures, or temperature changes.

In contrast, while other chart types like gauge charts and scatter charts present data in their own ways, they do not effectively illustrate trends over time. Gauge charts are typically used to show progress towards a goal or to display a single value in relation to a scale, such as performance metrics, and don’t convey temporal changes. Scatter charts are designed to show relationships and distributions between two quantitative variables rather than tracking a variable across time. A tile bullet chart, on the other hand, is used for comparing performance categories and does not convey time-dependent data changes either. Thus, the line chart stands out as the most suitable option for visualizing how data evolves over time.
