It IS possible to prevent exception throws, but it will require a little work on your part. dynamic_properties has a constructor of the form: dynamic_properties( const boost::function< std::auto_ptr

Does anyone have a code example of a reasonable implementation of this dynamic_property_map functor technique to read graphviz dot files with arbitrary properties? I've been trying to extract and adapt the bgl python library's nice read_graphviz function, which implements this dynamic_property_map functor technique, but it is still not functional after several hours of template struggles. I have been using a (long) hard-coded property list for read_graphviz in my code for the past year, but there are so many obscure dot file properties that it is still very hit-or-miss. Thanks.
