An area chart represents the quantitative analysis of a dataset. It is a plot just like a line chart, but the difference is that the area below the line had shade or color till the axis. We use differently shaded regions to compare the data.
Why do you need it?
An Area chart visualizes every data and compares two or more quantities. These charts help to show a trend over time when showing every point is not what concerns us. This visualization looks attractive and is effective to understand.
What kind of data you can visualize with it?
Assume you have a dataset of the average scores of all the students in two classes for a year, then this chart is beneficial. This can help us to see which class performs best for the whole year. By this, we can analyze which class doesn’t perform well and needs improvement by adopting the best measures.
