Thanks Volodya,

there are 2 issues that have confused me:
- compared to the other boost libraries like thread, date-time, ecc...,
graph lib requires to explicitly specify it in the list of the libs of
the project; there aren't any automatic linking of the lib;
- the name of the lib isn't 'libbgl-viz' like specified in the doc:

http://www.boost.org/doc/libs/1_31_0/libs/graph/doc/read-graphviz.html

   but is complying to the other boost lib names:
     - libboost_graph-vc80-mt.lib (release version);
     - libboost_graph-vc80-mt-gd.lib (debug version);

I haven't found this info anywhere in boost docs, but I've resolved
