Draw a directed graph using Sfdiagram

Question

Is there a way to position the nodes without specifying offset?

I want to draw a workflow( which is a directed graph). Is there a way to just specify the nodes and connectors between nodes using SourceNodeID and TargetNodeID and draw the graph without positioning the nodes myself?

Hi
Ragul,Requirement:
How to position the nodes automatically without setting positions to the nodes.You
can arrange and positioning the nodes by initialising the Layout to diagram.Code
snippet:

//Initialize layout Manager to arrange and position the nodes
  automatically.
  diagram.LayoutManager = new LayoutManager()
  {
      Layout = new DirectedTreeLayout()
      {
          HorizontalSpacing
  = 70,
          VerticalSpacing =
  50,
          Orientation =
  TreeOrientation.TopToBottom,
          Type =
  LayoutType.Hierarchical,
         
  AvoidSegmentOverlapping = false,
      },
  };
