Re: [boost] [bgl] write_graphviz without vertex_id

Hello Loïc I might be wrong, but since vertex descriptors are usually integers (and therefore its value type can be written to a stream), using identity_property_map as your vertex_id property map might do the trick. See http://www.boost.org/libs/property_map/identity_property_map.html for more information. Hope this helps ! Benoît
