Benefits & pitfalls

Benefits & pitfalls: bubble chart

  • Using area or volume to represent data can distort data values, and exaggerate differences between values. For example, if the radius of the circle is used to represent data values, the area of the circle will quadruple if the data values double. There is also an issue of 'perceptual scaling' - the tendency of people to underestimate areas.
