    <title></title>
    <script src="$base.contextPath/lib/kendoui/js/jquery.min.js"></script>
    <script src="$base.contextPath/lib/kendoui/js/kendo.all.min.js"></script>
</head>
<body>
<style>

</style>
    <div class="row" id="exmple">
        <div class="demo-section k-content wide">
            <div id="chart"></div>
        </div>
    </div>
<script>
        var data = [
            
                "source": "Hydro",
                "percentage": 22,
                "explode": true
            ,
            
                "source": "Solar",
                "percentage": 2
            ,
            
                "source": "Nuclear",
                "percentage": 49
            ,
            
                "source": "Wind",
                "percentage": 27
            
        ];

        function createChart() 
            $("#chart").kendoChart(
                title: 
                    text: "Break-up of Spain Electricity Production for 2008"
                ,
                legend: 
                    position: "bottom"
                ,
                dataSource: 
                    data: data
                ,
                series: [
                    type: "pie",
                    field: "percentage",
                    categoryField: "source",
                    explodeField: "explode"
                ],
                seriesColors: ["#03a9f4", "#ff9800", "#fad84a", "#4caf50"]
            );
        

        $(document).ready(createChart);
        $(document).bind("kendo:skinChange", createChart);
    </script>
</body>
