In general, bubble plots are not good visual aid, except when you happen to have data for which they work well. They try to represent an additional dimention in 2-D, so there are bound to be problems if there is not enough space to do this on a plot; additionally the scale is not linear, or something else we are use to for comparing large differences (in case of your data). It may be better at times to just label the data points, and let the reader choose the interpretation, without representing relative size graphically.

Please see a good book on Statistical Graphics.
