[Paraview] Python vector field/streamline script

[George Gerber]

Hi.

I would like to use Paraview to display velocity fields and streamlines 
of my Particle Image Velocimetry (PIV) measurements. Does an example 
python script exist for making a vector field plot from a numpy array or 
.csv data file? I could not find any example code on the Paraview wiki.

Any example code would be greatly appreciated.

Best regards
George
