A Bubble Chart is an extension of the XY Scatter Chart. It adds a 3rd variable to each point in the XY Scatter Chart.
For example, if you have a Scatter Chart that shows the relationship between the age of a house and its proximity to the city and want to add the value of the house (the 3rd variable), then a Bubble Chart will get you there.
The value of the house (the 3rd variable) will determine the size of the bubble, the age of the house is on the X-axis and the proximity to the city is on the Y-axis, as shown below.
