If you mean a graph as opposed to a vertex or edge property, my dot file 
presently doesn't have one, hence my code doesn't have a property for it.

I think the way to do this for an external resource is to:
   typedef std::map<std::string,std::string> StringToString;
   StringToString graphText;
   associative_property_map<Cost> graphTextProperty(graphText);
   ...

   dp.property("orientation", graphTextProperty)

You need one of the latter for each graph property type present in your 
graph.  The first parameter is the property name.

read_graphviz throws an exception if it encounters a property that 
doesn't have a "place" in the passed dynamic_properties object.

Note that I haven't tried this....
