My particles move around and their diameters change with as they do. Can anybody tell me what I can do to visualize them?

This is possible with paraview
 

This is possible with paraview (if the diameter is written, of course ;-) ):

Vary the size of the spheres by scalar, use the diameter as the scalarr and you should be there
