Hi David,

you can read the data with ReadList and plot it with ScatterPlot3D (from
the Graphics`Graphics3D` package).

There is an adaption of Tom Wickham-Jone's graphics tutorial in the web,
which
explains this in sections 2.1 (ReadList) and 2.3 (ScatterPlot3D). (The
graphics need Java and some time to load, but can be rotated in
real-time
once they are shown.)
The URL is:

http://theorie3.physik.uni-erlangen.de/~mkraus/tutorial/

The tutorial (or the web adaption) cover most common questions on
three-dimensional
Mathematica graphics (for example implicit plots, the argument of the
ColorFunction,
removing meshes, changing plot style with ParametricPlot3D, etc.)

But certainly it is easier to ask in this newsgroup! ;)

Greetings

Martin
