<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/raphael/2.1.2/raphael-min.js"></script>
<script src="morrisfile/morris.js"></script>
<link href="morrisfile/morris.css" rel="stylesheet" />

[Webmethod] 
public string googleAPIPieChart(DataTable dt, String chartTitle = null, string chartHeight = null, string chartWidth = null)
{
chartTitle = chartTitle ?? "Sample Pie Chart";
chartHeight = chartHeight ?? "250";
chartWidth = chartWidth ?? "250";
StringBuilder sb = new StringBuilder();
try
{
string sJsonData = Charts.ConvertDataTableToString(dt);
sb.Append("<div id=" + "\"" + "Pie" + "\"" + "></div>");
sb.Append(Environment.NewLine);
sb.Append(Environment.NewLine);
sb.Append("<script type=" + "\"" + "text/javascript" + "\"" + ">");
sb.Append(Environment.NewLine);
sb.Append("google.load(" + "\"visualization\"" + "," + "\"1\"" + "," + " " + "{" + " packages: " + "[" + "\"corechart\"" + "]});");
sb.Append(Environment.NewLine);
sb.Append("google.setOnLoadCallback(" + "drawChart" + ");");
sb.Append(Environment.NewLine);
sb.Append("function" + " " + "drawChart() {");
sb.Append(Environment.NewLine);
sb.Append("var data = google.visualization.arrayToDataTable([");
sb.Append(Environment.NewLine);
sb.Append(sJsonData);
sb.Append("]);");
sb.Append(Environment.NewLine);
sb.Append("var options = {");
sb.Append(Environment.NewLine);
sb.Append("title: " + "\'" + chartTitle + "\'" + ",");
sb.Append("legend: " + "\'" + "none" + "\'" + ",");
