title: Displaying Parallel Edges in Graphstream
body: <p>I have a multigraph, and I would like to be able to see each edge that goes from one vertex to another clearly. For example, when I have a graph with 2 vertices, and 2 edges going from the first to the second, I would like to see 2 arrows going from the first node to the second, instead of the arrows overlapping.</p>
  
  <p>This is my code currently, and you can see that I'm trying to have 2 edges connecting A and B:</p>
  
  <pre><code>import org.graphstream.graph.*;
  import org.graphstream.graph.implementations.*;
  import org.graphstream.ui.swingViewer.Viewer;
  
  public class Tutorial1 {
      public static void main(String args[]) {
          Graph graph = new MultiGraph("Test");
  
          graph.addNode("A");
          graph.addNode("B");
  
  
          graph.addEdge("1", "A", "B", true);
          graph.addEdge("2", "A", "B", true);
  
          Viewer viewer = graph.display();
      }
  }
  </code></pre>
  
  <p>Thanks for any help.</p>
