   In Pajek you can assign (read as input or compute) different properties to vertices:
     numerical properties as vectors
     ordinal properties as vectors or partitions
     nominal properties as partitions
   Vectors can be used to determine coordinates of vertices
       Operations / Vector / Put coordinate
   or size of vertices
       Draw / Draw - vector
   To define the unit size of vertices use (in Draw window)
       Options / Size / of vertices
   Partitions are represented by colors.
       Draw / Draw - partition
   to change colors use
       Options / Colors / partition colors

   To transform vector into partition use
       Vector / Make partition
