How can I access the position on the plane of the vertices from a given
Apollonius graph?

I'm a beginner with CGAL, I've been searching a lot in documentation but
haven't find what I need. I append some code as example:

---------------------------------------------------------------------------

/* Typedefs */
typedef CGAL::Cartesian<double> K;
typedef CGAL::Point_2<K> Point_2;
typedef CGAL::Apollonius_graph_filtered_traits_2<K> Gt;
typedef CGAL::Apollonius_graph_vertex_base_2<Gt> Vb;
typedef CGAL::Triangulation_face_base_2<Gt> Fb;
typedef CGAL::Triangulation_data_structure_2<Vb,Fb> Agds;
typedef CGAL::Apollonius_graph_2<Gt,Agds> Apollonius_graph;
typedef Gt::Site_2 Site_2;
typedef Gt::Site_2::Weight Weight;

/* Sites' position vector declaration */
std::vector<Point_2> points;
-- Code to fill points in here...

/* Point of vertices declaration */
std::vector<Point_2> ap_vertices;

/* Graph declaration */
Apollonius_graph ap;
/* Graph filling */
for (int i=0; i<points.size(); i++) {
    ap.insert(Site_2(points[i], Weight(10*i)));
}

Now, how can I access to the vertices (not the sites) of 'ap' to fill
'ap_vertices' with them?

Many thanks.
