Area Chart is an extension of Line Chart. It not only displays the series of data points, but also gives you a visual representation of volume.
#When to use Area Chart?
Area Chart is used when you want to compare the change of volumes over time between categories, or the distribution of categories as parts of a whole. Different area chart types will serve different purposes.
#Standard Area Chart
This is best used to grasp the quantity progression over time.
#Stacked Area Chart
Stacked Area Chart is best when you want to monitor the contribution of categories over time.
#100% Stacked Area Chart
This is best used to visualize the contribution of categories, when you do not care for the actual raw number.
#Create an Area Chart
