    val graph_attributes : t -> Graphviz.DotAttributes.graph list

Graph, vertex and edge attributes.
Vertex attributes

    val default_vertex_attributes : t -> Graphviz.DotAttributes.vertex list

Vertex attributes

    val vertex_name : V.t -> string

    val vertex_attributes : V.t -> Graphviz.DotAttributes.vertex list

Edge attributes

    val default_edge_attributes : t -> Graphviz.DotAttributes.edge list

Edge attributes

    val edge_attributes : E.t -> Graphviz.DotAttributes.edge list

    val get_subgraph : V.t -> Graphviz.DotAttributes.subgraph option

The box (if exists) which the vertex belongs to. Boxes with same names are not distinguished and so they should have the same attributes.
