  A visualization scheme for dynamics of a qudit polarization vector in a
time-dependent magnetic field is presented by solving equations for a density
matrix in Hermitian basis. This is realized by means of mapping solution for
the polarization vector on the three-dimensional spherical curve (vector
hodograph).
  The obtained results obviously display the interference of precessional and
nutational effects on the polarization vector in a magnetic resonance. The
study can find the practical applications in a magnetic resonance and 3D
visualization of computational data.
