Best application for 3D graphing (heat maps, contours, bump maps and so on)?

I have some data, mostly 3D and the data in higher dimensions can generally be reduced to 3D for analysis.
A typical dataset has a value for several hundred (x,y,z) triples where I want to map z as a function of x and y, in a heat map, bump map, or contour form. The actual form doesn't matter... it just needs to be easily readable.
To take a specific example, I could have x = 1, 2, 3 ... 39, 40 and y = 10, 20, 30 ... 490, 500, with z varying between -500 and +500. I'd like to view this data as an (x, y) grid with the z values represented as heights, or colors, or something else.
I've tried both Excel and Numbers and neither really cuts it. I don't want to shell out for MatLab or anything like that. So I'm wondering if there's a good opensource/freeware/shareware solution to this?
I'm mosty Mac but happy to run a Windows app in VMWare.
