Please look at libs/graph/example/graphviz.cpp in your Boost source tree. 
The important part you need to change is the top of main() where the id 
and weight properties are registered.  You should change those to your own 
property maps and names.  You should then be able to do a read_graphviz 
call similar to the one in that example.
