Learn how to describe a line graph.
Definition
A chart type called a line graph is used to display data that evolves over time. We create line graphs by connecting a number of points together using straight lines. It is also known as a line graph. The 'x' and 'y' axes' are the two axes that make up the line graph.

Example
The graph shows patterns in music purchasing trends from 2011 to 2018. It offers three distinct approaches: downloading, streaming, and purchasing CDs.
Overall, the number of music downloads and physical sales has been falling. While the former began to decline in 2014, the latter has been declining since 2011. But since 2013, the number of people streaming music has sharply increased.
At 55% of total sales in 2011, CDs accounted for the majority of music sales. Streaming, on the other hand, was extremely uncommon, at 5 percent. Additionally, even though people had begun downloading music, it only accounted for 35% of total purchases. Downloads increased as CD sales started to decline. They grew steadily, and in the middle of 2013, downloads surpassed physical sales. During the same time frame, streaming doubled to 10%, but after that it began to increase significantly.
By 2018, downloads had decreased to 30% of sales from their 2014 peak of roughly 43%. This was a little bit more than physical sales, which fell to 25%. On the other hand, streaming surpassed both of them and represented slightly over 40% of revenues in 2018.
Conclusion
A line graph is a graphical representation of data that changes over time. It is typically used to visualize data that changes over a period of time, such as temperature, stock prices, or election results. Line graphs can be used to show trends, relationships, and comparisons.
