Re: [Boost-users] read_graphviz with a simple graph

If I have a graph with no vertex properties or edge properties:

adjacency_list<vecS, vecS, undirectedS>

can I read a .dot file into it with read_graphviz?

I tried:

dynamic_properties dp; Graph g; read_graphviz(fileinput, g, dp);

but it throws an exception "Property not found: node_id".

I tried to add

property_map<Graph, vertex_name_t>::type name = get(vertex_name, g); dp.property("node_id",name);

but I get a compiler error "No match for operator<<"

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. -- Jeremiah Willcock
