    Allows sets of points to be positioned over a sheet coordinate
    system. Each points may optionally be associated with a chosen
    numeric value.

    The input data can be a Nx2 or Nx3 Numpy array where the first two
    columns corresponds to the X,Y coordinates in sheet coordinates,
    within the declared bounding region. For Nx3 arrays, the third
    column corresponds to the magnitude values of the points. Any
    additional columns will be ignored (use VectorFields instead).

    The input data may be also be passed as a tuple of elements that
    may be numpy arrays or values that can be cast to arrays. When
    such a tuple is supplied, the elements are joined column-wise into
    a single array, allowing the magnitudes to be easily supplied
    separately.

    Note that if magnitudes are to be rendered correctly by default,
    they should lie in the range [0,1].

    A VectorField contains is a collection of vectors where each
    vector has an associated position in sheet coordinates.

    The constructor of VectorField is similar to the constructor of
    Points: the input data can be an NxM Numpy array where the first
    two columns corresponds to the X,Y coordinates in sheet
    coordinates, within the declared bounding region. As with Points,
    the input can be a tuple of array objects or of objects that can
    be cast to arrays (the tuple elements are joined column-wise).

    The third column maps to the vector angle which must be specified
    in radians. Note that it is possible to supply a collection which
    isn't a numpy array, whereby each element of the collection is
    assumed to be an iterable corresponding to a single column of the
    NxM array.

    The visualization of any additional columns is decided by the
    plotting code. For instance, the fourth and fifth columns could
    correspond to arrow length and colour map value. All that is
    assumed is that these additional dimension are normalized between
    0.0 and 1.0 for the default visualization to work well.

    The only restriction is that the final data array is NxM where
    M>3. In other words, the vector must have a dimensionality of 2 or
    higher.
