Great! thank you for all the effort

Actually they are used to display additional information for a polygon 
layer. This polygon layer represents parts of a city. For every part of 
the city there different values apply. Think about the maximum height 
which is allowed for buildings and the maximum height on which a gutter 
may be placed.
The circles get important if you want information about a layer(the 
people are used to have this information on their map's so it will be a 
hard job talking them out of this idea ;) )
