I was able to find the answer from a previous post. Thanks to thoes who might have replied... I have attached the code:

private void CreateHostObject(Host host, Point pt)
       {
           Box icon = flowChart.CreateBox(pt.X, pt.Y, 10, 10);
           icon.Image = Properties.Resources.host_n_16_3;
           icon.FitSizeToImage();
           icon.Transparent = true;

           SizeF labelSize = GetLineSize(host.ServerName, flowChart.Font);
           Box label = flowChart.CreateBox(pt.X - 16, pt.Y + 10, labelSize.Width, labelSize.Height);
           label.Transparent = true;
           label.FrameColor = Color.Black;
           label.IgnoreLayout = true;
           label.Text = host.ServerName;

           RectangleF rcNode = icon.BoundingRect;
           RectangleF rc = label.BoundingRect;
           rc.X = rcNode.X + rcNode.Width / 2 - rc.Width / 2;
           label.BoundingRect = rc;

           Group g = flowChart.CreateGroup(icon);
           g.AttachToSideMiddle(label, 2);
       }

       private SizeF GetLineSize(String s, Font f)
       {
           Graphics g = flowChart.CreateGraphics();
           g.PageUnit = flowChart.MeasureUnit;
           SizeF size = g.MeasureString(s, f);
           g.Dispose();
           return size;
       }
