A bubble chart is a type of chart that displays three dimensions of data. Each entity with its triplet (v1, v2, v3) of associated data is plotted as a disk that expresses two of the vi values through the disk's xy location and the third through its size. Bubble charts can facilitate the understanding of social, economical, medical, and other scientific relationships. The given graph represents a bubble chart. Along with the usual x,y values, we can define another dimension, such as importance, and can use the size of each disk to denote the importance of each disk. Companies can use this type of chart to plot data that has 3 associations or dimensions. A typical example would be the geographical location of various employees where the size of the disk denotes the importance of each employee.
