What you need to do is send the command to the google charts api and convert the response to an image like below, and then you can take the image object and write it to a file or perform any operation you want:
string ChartURL = "http://chart.apis.google.com/chart?";
ChartURL += "chxr=0,0," + MaxX + "";
ChartURL += "&chxt=y";
ChartURL += "&chbh=a";
ChartURL += "&chs=" + ChartWidth + "x" + ChartHeight + "";
ChartURL += "&cht=bvg";
ChartURL += "&chco=" + ChartColors + "";
ChartURL += "&chds=" + ChartDataRange + "";
ChartURL += "&chd=t:" + ChartValues + "";
ChartURL += "&chdl=" + ChartLegend + "";
ChartURL += "&chtt=" + ChartTitle + "";
HttpWebRequest myRequest = WebRequest.Create(ChartURL) as HttpWebRequest;
HttpWebResponse ServerResponse = myRequest.GetResponse() as HttpWebResponse;
Stream ResponseStream = myRequest.GetResponse().GetResponseStream();
return System.Drawing.Image.FromStream(ResponseStream);
