Bubble charts (sometimes called XYZ plots or point maps) allow to you change the size of a symbol based on a third value. These charts can be useful if you need to show three types of data per data point. The X and Y are the same as they are for normal graphs but the Z value then controls the size of the point/bubble.
What I like about this video is that is shows you how to add images into the bubbles and label the points with you own labels. This is really useful and as you will see from the video creates a great looking chart.
