The strategy for doing that is to create a dynamic_properties object, add an entry to it for the "style" edge property and some property map, and then pass that to write_graphviz_dp. An example of what you want to do is in libs/graph/example/graphviz.cpp; see how the "weight" property is handled. In your case, the value type of the property would be std::string.

Thanks Jeremiah, Here is what I tried: #include <iostream> #include <string> #include <boost/graph/undirected_graph.hpp> #include <boost/graph/graphviz.hpp> struct StyleProperty { std::string style; } typedef boost::undirected_graph<boost::no_property, StyleProperty> Graph; int main() { Graph g; Graph::vertex_descriptor v0 = g.add_vertex(); Graph::vertex_descriptor v1 = g.add_vertex(); Graph::vertex_descriptor v2 = g.add_vertex(); StyleProperty styleInvisible; styleInvisible.style = "invis"; StyleProperty styleNormal; styleNormal = "normal"; boost::add_edge(v0,v1,styleInvisible, g); boost::add_edge(v1,v2,styleNormal g); boost::dynamic_properties dp; dp.property("style", get(&StyleProperty::style, g)); boost::write_graphviz_dp(std::cout, g, dp, "style"); return 0; } However, I get an exception "dynamic property get cannot retrieve value for property: style." Can you see where I have gone wrong? Thanks, David
