The bubble chart is a variation of a Scatter chart and its information is pointed as a bubble. And in case your every collection has three information as proven as below, making a Bubble chart can be a sensible choice to indicate the information collection vividly. Similar to a scatter chart, a bubble chart doesn’t use a class axis — each horizontal and vertical axes are valued axes. Along with the x values and y values which can be plotted in a scatter chart, a bubble chart plots x values, y values, and z (dimension) values.
