        {
            var w = 800;
            var h = 600;

            // add canvas to the div with id = "target" (defined in MainPage.html)
            Element.GetById("target").AppendChild(canvas);

            // get the 2D context for the canvas, which contains all the draw methods
            var context = canvas.Get2DContext();

            // draw background rect
            context.FillStyle = new RgbStyle(0xcc, 0x66, 0x99);
            context.FillRect(0, 0, w, h);
            context.LineWidth = 2;

            // draw flowers
            context.StrokeStyle = new RgbStyle(0x33, 0x33, 0x33);

            context.FillStyle = new RgbStyle(0xff, 0xff, 0);
