Looking for a 3D graphics program to draw balls in space

[el_hijoeputa]

Is there exist a program that I just give the (x,y,z) coordinates, and the program draw me a 3D ball where I asked. I will use it to draw a crystall consisting of balls.

I need the program to help me visualize the structure of a crystal, and to draw a picture of a crystall, and identify the planes of atoms (with miller indices) and impress everyone in an oral presentation :)
