In this example, I am using a two-dimensional array to provide attributes for a graph from Fusion Charts :
    /*Store sales data*/
   string[,] arrData = new string[4, 2];
        arrData[0, 1] = “Annual Cash Compensation”;
        arrData[1, 1] = “Annual LTI Compensation”;
        arrData[2, 1] = “Current Financial Protection”;
        arrData[3, 1] = “Future Financial Security”;
/*Store sales amounts*/
    arrData[0, 2] = PercentDC.ToString();
        arrData[1, 2] = PercentLT.ToString();
        arrData[2, 2] = PercentCFP.ToString();
        arrData[3, 2] = PercentFFS.ToString();
    /*Now, we need to convert this data into XML. We convert using
   string concatenation.*/
    string strXML = “”;
    /*Convert data to XML and append*/  
   for(int pieI = 0; pieI <= arrData.Length - 1; pieI++) 
{ strXML = strXML &  “
