   d.vect.chart displays charts for GRASS vector data in the active frame
   on the graphics monitor.

ÐÐ ÐÐÐЧÐÐÐЯ

   The charts are positioned as follows:
     * vector points: on point position
     * vector lines: on line centers
     * vector areas: on area centroids

   Bar charts are placed with their lower edge starting from the
   y-coordinate of the feature being symbolized, and centered with respect
   to the x-coordinate. The -c flag can be used to center the bar chart in
   both x and y directions.
   The 'sizecol' parameter is proportionate to the radius.
   The optional max_ref parameter accepts a list of values that represent
   the maximum value for each column listed in the values for the
   parameter columns. These values are used to create a framed bar plot if
   ctype is bar (See Example 2).
