[Boost-users] [BGL] How do I iterate over a labeled graph?

I am trying to iterate over my labeled_graph like so:

struct Vertex
{
        std::string vertType;
};
typedef Graph::vertex_iterator VertexIter;
VertexIter vertexIter, vertexEnd;
for (tie(vertexIter, vertexEnd) = vertices(graph); vertexIter != vertexEnd;
vertexIter++)
{
        std::string vertexType = graph[*vertexIter].vertType;
}

However, I get a compiler error saying that graph has no operator [] that
accepts an unsigned int.  How should I be doing what I'm trying to do?
