[Paraview] ASCII data visualization in paraview

[Cory Quammen]

SaiD,

The VTK legacy file format, which supports an ASCII option, is fairly
straightforward. You may even get lucky and be able to adapt the file
you attached (I haven't looked at it) by simply adding some header
information. Documentation for that format is located at
http://www.vtk.org/wp-content/uploads/2015/04/file-formats.pdf

HTH,
Cory
