Code

            return Fluently.CreateDirectedGraph()
                .TheDefaults.ForEdges.Are(x => x.WithLabel("Default Color Blue").WithColor(Color.Blue))
                .TheDefaults.ForNodes.Are(x => x.WithShape(NodeShape.Diamond).WithColor(Color.Green).WithLabel("Green Diamond"))
                .Nodes.Add(x =>
