Correct Answer:

It connects individual data points with a continuous line to show how a metric changes over time

Explanation:

Line charts show how a metric changes over time by plotting data points along a timeline and drawing a continuous line through them. The connected line emphasizes the direction and rate of change—upward slopes mean growth, downward slopes indicate decline, and flat sections show stability. Because the points are linked in order, you can easily spot trends, patterns, and how quickly values rise or fall. You can also compare multiple series by using more than one line, though too many lines can clutter the chart. This approach is distinct from area charts (which fill beneath the line), charts that show parts of a whole, and charts that display frequencies within ranges.
