The following works, but it seems very confusing. I tried the two
commented lines separately but they don't compile. Is this the
recommended method?

  typedef boost::property < boost::vertex_name_t, std::string> VertexProperty;
  typedef boost::adjacency_list < boost::vecS, boost::vecS,
boost::directedS, VertexProperty> graph_t;

  //typedef boost::adjacency_list < boost::vecS, boost::vecS,
boost::directedS, boost::no_property> graph_t;
  //typedef boost::adjacency_list < boost::vecS, boost::vecS,
boost::directedS, boost::null_property_map> graph_t;

  graph_t graph;

  boost::dynamic_properties dp;
  boost::property_map<graph_t, boost::vertex_name_t>::type name =
get(boost::vertex_name, graph);
  dp.property("node_id",name);

  bool status = boost::read_graphviz(stream,graph,dp,"node_id");
