[GRASSLIST:1013] nviz and vector points

Hi,

I'm trying to draw some vector points on a 3D surface. I've managed to
draw the points in the surface, but I don't know how can I show attributes
of the points in the 3D representation (They are cities so I need to show
their names).

Is there any way to solve this problem?

Thanks for the attention;
