This C# tutorial demonstrates how to generate the Microsoft Bubble Chart (both 2D and 3D types), and insert the MS Bubble Chart as image to PDF Page.

Developers can insert the Bubble graph to PDF in any location, maybe on the top of PDF page or at the right bottom of page in the PDF file. The following C# .NET demo code shows how to create and save Microsoft Bubble Chart to PDF document programmatically.
Please note, before developers using the chart making code, the MS Chart Control should be referred to your .NET application:

• System.Windows.Forms.DataVisualization.Charting (for .NET WinForms project)
• System.Web.UI.DataVisualization.Charting (for ASP.NET application)

Make and render Microsoft 2D Bubble Chart to PDF in C# code.

public static void InsertMSChartToPDF()
{
    // Create a new PDF document.
    PdfDocument document = new PdfDocument();

    // Create an empty page in this document.
    PdfPage page = document.AddPage();

    // Obtain an XGraphics object to render to
    XGraphics g = XGraphics.FromPdfPage(page);

    // Create bubble chart stream object
    Stream chartStream = CreateMSBubbleChart();

    // Convert chart stream to XImage object
    XImage chartImage = XImage.FromStream(chartStream);

    // Insert the chart image to pdf page in any position
    g.DrawImage(chartImage, 50, 50);

    // Save and show the document
    document.Save("MSBubbleChart.pdf");
    Process.Start("MSBubbleChart.pdf");
}

public static Stream CreateMSBubbleChart()
{
    // Create ms chart object
    Chart chart = new Chart();

    ChartArea chartArea = new ChartArea();
    Series series1 = new Series();
    Series series2 = new Series();

    // Input Data Point
    DataPoint dataPoint1 = new DataPoint(0, 5);
    DataPoint dataPoint2 = new DataPoint(0, 8.5);
    DataPoint dataPoint3 = new DataPoint(0, 9);
    DataPoint dataPoint4 = new DataPoint(0, 7);
    DataPoint dataPoint5 = new DataPoint(0, 5);
    DataPoint dataPoint6 = new DataPoint(0, 6);
    DataPoint dataPoint7 = new DataPoint(0, 4);
    DataPoint dataPoint8 = new DataPoint(0, 5);
    DataPoint dataPoint9 = new DataPoint(0, 3.5);
    DataPoint dataPoint10 = new DataPoint(0, 4);

    // Set series1 with data, color, chart type and name
    series1.BorderColor = Color.FromArgb(180, 26, 59, 105);
    series1.ChartType = SeriesChartType.Bubble;
    series1.Color = Color.FromArgb(220, 65, 140, 240);
    series1.Name = "Series1";
    series1.MarkerSize = 10;
    series1.MarkerStyle = MarkerStyle.Circle;
    series1.Points.Add(dataPoint1);
    series1.Points.Add(dataPoint2);
    series1.Points.Add(dataPoint3);
    series1.Points.Add(dataPoint4);
    series1.Points.Add(dataPoint5);

    // Set series2 with data, color, chart type and name
    series2.BorderColor = Color.FromArgb(180, 26, 59, 105);
    series2.ChartType = SeriesChartType.Bubble;
    series2.Color = Color.FromArgb(220, 252, 180, 65);
    series2.Name = "Series2";
    series2.MarkerSize = 10;
    series2.MarkerStyle = MarkerStyle.Square;
    series2.Points.Add(dataPoint6);
    series2.Points.Add(dataPoint7);
    series2.Points.Add(dataPoint8);
    series2.Points.Add(dataPoint9);
    series2.Points.Add(dataPoint10);

    // Bind series data to chart
    chart.Series.Add(series1);
    chart.Series.Add(series2);

    // Set chart 3D style
    chartArea.Area3DStyle.Enable3D = false;
            
    // Bind chart area to chart object
    chart.ChartAreas.Add(chartArea);

    // Modify chart size
    chart.Size = new Size(400, 300);

    // Render chart graphics to stream
    MemoryStream ms = new MemoryStream();
    chart.SaveImage(ms, ChartImageFormat.Png);

    return ms;
}       

Paint and insert MS 3D Bubble Chart to PDF in C# code.

All the step and code are the same as above, only need change the chartArea.Area3DStyle.Enable3D = false; in the "CreateMSBubbleChart()" to the C# code below.

chartArea.Area3DStyle.Enable3D = true;
chartArea.Area3DStyle.Inclination = 15;
chartArea.Area3DStyle.IsRightAngleAxes = false;
chartArea.Area3DStyle.Perspective = 10;
chartArea.Area3DStyle.Rotation = 10;
chartArea.BackColor = Color.WhiteSmoke;
