What is a Line Chart?

A line chart displays information as a series of data points connected by straight lines. It's primarily used to show trends over time or continuous data, making it easy to see patterns, increases, decreases, and fluctuations.

When to use Line Charts?

Line charts are ideal for showing trends over time, displaying continuous data, comparing multiple data series, or when you want to emphasize the rate of change rather than individual values.

When might Line Charts be inappropriate?

Line charts shouldn't be used for discrete categories without natural order, when data points are independent of each other, or when you want to compare parts of a whole.

What is the importance of Line Charts in Visualization?

Line charts are excellent for storytelling with data, especially when showing change over time. They're intuitive to read and effective for identifying trends, patterns, and anomalies in time-series data.
