I think you will need some kind of property to store the vertex names from Graphviz; you might be able to use null_property_map for that (from <boost/graph/property_maps/null_property_map.hpp>) though.

Hm, I tried:
#include <boost/graph/property_maps/null_property_map.hpp> ...
typedef boost::adjacency_list < boost::vecS, boost::vecS, boost::directedS, VertexProperty> Graph; boost::dynamic_properties dp; dp.property("node_id", boost::make_null_property<Graph::vertex_descriptor, std::string>() );
but I get a compiler error on that last line (i.e. if I comment it the error goes away) that says:
"error: no matching function for call to 'get(boost::null_property_map<unsigned int, std::basic_string<char> > &, unsigned int)"
I don't know what that means ?
Apparently null_property_map is write-only, so it doesn't have a get() function; I hadn't realized that. Please try dummy_property_map (from boost/property_map/property_map.hpp) instead, or if that doesn't work, static_property_map or ref_property_map from the same file. -- Jeremiah Willcock
