Hi,

I'm trying to output an image showing subgraphs [0] using
write_graphviz() in boost 1.48.0.  I've tried to modify an example [1]
by adding a write_graphviz() call. eg...

    std::ofstream ofs("out.dot");
    const char* names[] = { "A", "B", "C", "D", "E", "F" };
    write_graphviz(ofs, G0.m_graph, make_label_writer(names));

This works fine for displaying the underlying graph, but no subgraphs
are shown.  When I do the following...

    write_graphviz(ofs, G0, make_label_writer(names));

I get a host of errors including...

    include/boost/graph/graphviz.hpp:377: error: no matching function
for call to ‘get(boost::label_writer<const char**>&, Vertex&)’

I notice a comment in graphviz.hpp [2] 'requires graph_name graph
property' so I had a look at the subgraph_properties.cpp example [3].
This seemed to only be showing vertex properties but didn't compile
out of the box.  Is it possible for someone experienced in
boost::graph to post a modified version of [1] that can produce
something like image [0], or point me in the right direction?

Thanks,
Chris
