Automatic layout without node position

Question

Hi all. I was testing this great library, trying to convert an old project made with another one. In this project I didn't specify nodes size and position, letting the library doing it automatically.

I have seen that there are several demos (for example Demo.yFiles.Graph.IncrementalHierarchicGrouping and Demo.yFiles.Graph.Folding) , but in all of them it seems that nodes are defined in agraphml file containing their coordinates and other stuff to.

In fact, if I populate the graph with code like the CreateInitialModelGraph method of Demo.yFiles.Graph.Folding demo:

// create some nodes and groups
      INode g0 = groupedGraph.CreateGroupNode();
      INode g1 = groupedGraph.CreateGroupNode(g0);
      INode c1 = groupedGraph.CreateNode(g0);
      INode c2 = groupedGraph.CreateNode(g0);
      INode c3 = groupedGraph.CreateNode(g1);
      INode c0 = graph.CreateNode();

      // create some edges
      graph.CreateEdge(c1, c2);
      graph.CreateEdge(c0, g0);
      graph.CreateEdge(c0, c1);
      graph.CreateEdge(c2, c0);
      graph.CreateEdge(c2, c3);
      graph.CreateEdge(g1, c0);

I get every nodes in the same position.

Is there any way to automatic layout nodes withous specifying their position and size?

Thanks
