A bubble chart is a variation of a scatter chart in which the data points are replaced with bubbles, and an additional dimension of the data is represented in the size of the bubbles. A bubble chart can be used to plot upto 4 variables i.e. X axis values, Y axis values, Size of the bubble and Color of the bubble A bubble chart is used to visualize a data set with two to four dimensions. The first two dimensions are visualized as coordinates, the third as color and the fourth as size and color We can use a bubble chart instead of a scatter chart if the data has three data series that each contains a set of values. The sizes of the bubbles are determined by the values in the third data series.

1. Three Values Per Data Points: Three values are required for each bubble. These values can be in rows or columns on the excel, but they must be in the following order: x value, y value, and then z value.
2. Multiple Data Series: Plotting multiple data series in a bubble chart is similar to plotting multiple data series in a scatter chart. Scatter charts use sets of x values and y values, but bubble charts use sets of x values, y values, and z values.
