    function AsyncLoad(V_tag,V_src)
        {
            if (V_tag == "script") {
                var s = document.createElement('script');

                s.async = true;
                s.src = V_src;
                var x = document.getElementsByTagName('script')[0];
                x.parentNode.insertBefore(s, x);
                s.onload = function () {
                    if (V_src == "../Content/Scripts/jquery-2.1.1.min.js") {
                        AsyncLoad("script", "../Content/Scripts/public-effect.js");
                        AsyncLoad("script", "../Content/Scripts/d3.v3.min.js");
                        
                        AsyncLoad("script", "../Content/Scripts/Common.js");

                        AsyncLoad("script", "../Content/Scripts/mobilePie.js");
                    }
