Hi,

The BubbleScale is an option to BubbleChart3D that specifies how the 
scale of each bubble should be determined from the value of each data 
element.

Look at the example here ($Version = "8.0 for Mac OS X x86 (64-bit) 
(October 5, 2011)");

data = {{1, 1, 1, 1*^-7}, {2, 2, 2, 1*^-8}, {3, 3, 3, 1*^-9}, {4, 4, 4, 1*^-10}};
BubbleChart3D[data, BubbleScale -> "Diameter", BubbleSizes -> Medium]

How is the diameter of the bubbles actually calculated/related to the values of each data element  when the BubbleScale->"Diameter"?
