Bubble Charts
Bubble charts are essentially a point plotted in a grid representing three dimensions. The value of the Z-
axis is expressed by the size of the bubble. Imagine that the bubble exists in a 3-D plane and will appear
large if it is closer to you. Actually the “bubble” can be a circle, square, triangle, diamond, or cross shape.
