A bubble graph lets you compare items on a list to see how many times they are associated with another concept.
In this example, I have compared football players and their goals and fouls:
You can see that Luis Suarez is mentioned for both goals and fouls as he is one of the top scorers in the Premier League, and also involved in a large number of fouls. On the other hand, Wayne Rooney is mostly known for his goal scoring than his dirty play.
How to create a bubble graph

I can at any time change one or both of the axes to modify the analysis I run. Here are some other bubble graphs I have generated using the same list of players:
