Maybe like this?:
Let the amount of shown values decide about the angle and the radius shows the amount?
I don't know if that's what's being suggested, but IMHO the "normal" pie graphs in your first example are much easier to comprehend.
But, yes a system that produced 10 farming 20 RP & 5 PP (35 total) would obviously have a smaller circle than a planet that produced 50 farming 10 RP & 25 PP (85 total).
The relationship between the circle radius and the quantity measured might not be fixed however. The amount of RP (for instance) produced in a single system might be 1000s of times larger in the end-game than the beginning. In order to make early-game differences noticeable, the scale of the spheres could be keyed to what the largest current quantity is. I.E. in the early game the system with the highest RP (in the galaxy, or simply in the known galaxy?) would display a circle of the maximum size, and all other systems would have proportionally smaller circles. In the end game, the system with the highest RP would have a circle of the same maximum size as early game, and all other systems would be rated proportionately, even though the relationship between # of RPs to radius of circle has changed.
Don't know if i'm explaining this well, but the idea is pretty straight forward.
