[vtkusers] visualizing scattering of random points

[Mike Jackson]

You should be able to read the points into an unstructured grid but  
do not build the lines or connectivity. Then in ParaView, load the  
data set and then apply a "Glyph" filter which puts a sphere at each  
point. Then color the spheres by the scalar value attached to each  
point.
    _How_ you load the data into paraview is left as an exercise to  
the reader. Hint - If your data is NOT already in a format that  
ParaView understands then writing a legacy VTK file is the easiest  
route to get your data into ParaView.
