Before someone begins to tackle this:

1. I corrected the format of the data file.

2. I can generate a plane with:

vtkStructuredPointsReader data
    data SetFileName $VTK_DATA/structured_points_test.vtk
vtkStructuredPointsGeometryFilter plane
    plane SetInput [data GetOutput]
    plane SetExtent 0 6 0 6 0 1
 
vtkLookupTable lut
 
vtkPolyDataMapper planeMapper
    planeMapper SetLookupTable lut
    planeMapper SetInput [plane GetOutput]
    planeMapper SetScalarRange 1 5 

3. ...but I am still trying to figure out how to map the color scalars.
