    // Create a page.
    PdfPage page = document.AddPage();

    // Generate a 2d area chart graph
    Chart chart = AreaChart();

    // Create a chart frame, set chart location and size
    ChartFrame chartFrame = new ChartFrame();
    chartFrame.Location = new XPoint(30, 30);
    chartFrame.Size = new XSize(500, 600);
    chartFrame.Add(chart);

    // Render chart symbols into pdf page
    XGraphics g = XGraphics.FromPdfPage(page);
    chartFrame.Draw(g);

    // Save and show the document           
    document.Save("AreaChart.pdf");
