Short how to use OpenDiagram Flowchart

frmFlowChart.cs

			Model model = diagram1.Model;
			diagram1.Model.SetSize(new Size(1000, 1000));

			Shape shape = new Shape();
			shape.Location = new PointF(10, 20);
			//model.Shapes.Add("a1", shape);

            Flowchart f = (Flowchart)diagram1;
            shape = f.AddFlowShape(shape.Location, FlowchartStencilType.Terminator);
            shape.Label = new Label("kaas");
            var p = f.AddDecision(shape, "test1", "test2", FlowchartStencilType.Process, "test3", FlowchartStencilType.Card);
            p.FalseLine.Label = new Label("no");
            p.TrueLine.Label = new Label("yes");
            p.DecisionShape.Label = new Label("wat?");
