Description
I'm trying to horizontal align subgraph nodes, without success. Code is:
`
using System.Linq;
graph.AddEdge("A", "B");
graph.AddEdge("A", "C");
graph.AddEdge("A", "D");
Subgraph hello = new Subgraph("hello");
graph.RootSubgraph.AddSubgraph(hello);
hello.AddNode(graph.FindNode("A"));
hello.AddNode(graph.FindNode("B"));
hello.AddNode(graph.FindNode("C"));
hello.AddNode(graph.FindNode("D"));
graph.LayerConstraints.PinNodesToSameLayer(hello.Nodes.ToArray());`
I suspect that by default all nodes of a subgraph belong to the same layer (please correct me if I'm wrong) and that's why my code doesn't work, while SameLayerSample does. But I cannot find a solution to horizontal align subgraph nodes, considering that graph LayerDirection has to beTB (TopBottom).

Research direction
Start with the provided Subgraph example and compare it with SameLayerSample, focusing on LayerConstraints.PinNodesToSameLayer and the graph's TB LayerDirection. Determine how horizontal alignment of the subgraph nodes is expected to work while preserving top-to-bottom layout, and verify the result with an equivalent graph example.
