Each bubble is a different brand, positioned on the graph more or less close to each other according to how many respondents they use them together (i.e. broadband from Provider 1 + landline from Provider 1 + mobile from Provider 2 + TV from Provider 5). Clustering they show what groups of services are more likely to be used together. In particular if a brand orbits on the outer circles, it is more likely to have loyal customers, using only its services, while the closer it gets to center the more likely to be used together with any other brand. Light beams from each bubble point towards the other services the respondents declared to use. A wider ray shows a higher number of different services used with the source one.
