Or, try out the example of a python programmable reader that I've just posted to the wiki. http://www.paraview.org/Wiki/Here_are_some_more_examples_of_simple_ParaView_3_python_filters.
To use it, open up Source->Programmable Source, set the output type to Poly Data, paste in the text, correct the filename, and in your case change the separator from "," to " ". Then apply the glyph filter. As Ken suggested.
