Visualization of variable combinations

What is the best way to visualize variables each of them with a certain range:

Following example:

possible values for ...

1. variable 1: [1,2,3,4]
2. variable 2: [40,50,60]
3. variable 3: [100k, 150k, 200k]

and now, for each combinations I get a certain value, for example the combination [V1: 2, V2:50, V3: 200k] leads to a percentage of 68%.

How do I visualize all of the possible combinations in a comprehensive way? Until now, I was only thinking about a Parallel Coordinate Plot, but does anybody have other idea?

Thanks a lot.
