Things I’d like to see: 4 dimensional isoquant

Neoclassical production function Y = f(K,L) giving us a basic, two-axis isoquant with technological advances pushing us to lower isoquants:


Pretty basic.

Now taking materials and energy considerations into account Y = f(K,L,E,M) which can’t be represented on a two-dimensional surface without lumping three of the factors together to tease out whatever relationship you’re trying to represent graphically.

I don’t know how useful it would be to see all four constraints mapped separately, but I think it would look pretty cool if it could be done. Alas, I am neither a graphics expert nor mathematician, so I’ll leave the feasibility discussion to others…
