What I had in mind for a cool and useful plug-in or feature. A big circle cut into rings, where if a object is within this ring, it increases this variable. The further in, the bigger the number. Here are some attributes for it as well:
MinVariableNum: The smallest number allowed for variable scaling.
MaxVariableNum: The largest number allowed for variable scaling. Is also Base Variable
GeneratedRings: The total rings the circle can be cut into. Limited at 50.
GeneratedSize: Scalable in the layout editor, this just tells you how big it is right now, and can be edited here as well.
This is just an idea/Concept. I don't know if there is something like this already, but if there is, tell me.
