trace – How to draw four data sets

a = RandomReal[{-1, 1}, 100];
b = RandomReal[{10, 20}, 100];
c = RandomReal[{100, 200}, 100];
d = RandomReal[{50, 60}, 100*100*100];

I have a simple program that generates 4 data sets. Now I have to represent this data in a sensible way. Lists a, b and c as dimensions 1 cross 100, and dimension d is 100 * 100 * 100. How to make a sensitive plot with this data. We have difficulty representing anything beyond 3D space, is there anything that Mathematica can offer for visualization?
