[Paraview] Visualizing a .csv

[Utkarsh Ayachit]

Your csv has all numerical values in quotes ("). That's resulting in
treating those values are strings instead of numbers. Remove the
quotes from all numerical values and it should load it in correctly.
Also there are "," in  place of decimal points. You may want to fix
that too.
