    directed_graph<VertexProp, EdgeProp, GraphProp>

The `directed_graph` class template is a simplified version of the BGL adjacency list. This class is provided for ease of use, but may not perform as well as custom-defined adjacency list classes. Instances of this template model the BidirectionalGraph, VertexIndexGraph, and EdgeIndexGraph concepts.

### Example

A simple examples of creating a directed_graph is available here `libs/graph/example/directed_graph.cpp`.

      typedef boost::directed_graph<> Graph;
      Graph g;
      boost::graph_traits<Graph>::vertex_descriptor v0 = g.add_vertex();
      boost::graph_traits<Graph>::vertex_descriptor v1 = g.add_vertex();

      g.add_edge(v0, v1);

### Template Parameters

Parameter | Description | Default
--- | --- | ---
`VertexProp` | A property map for the graph vertices. |
`EdgeProp` | A property map for the graph edges. |
`GraphProp` | A property map for the graph itself.

### Where Defined

`boost/graph/directed_graph.hpp`
