    $(document).ready(function () {

        $.getJSON("/Dashboard/GetData/", function (data) {
            var chart = new CanvasJS.Chart("chartContainer", {

                data: [
                {
                    // Change type to "bar", "splineArea", "area", "spline", "pie",etc.
                    type: "column",
                    dataPoints: data
                }
                ]
            });

            chart.render();
        });

    });
</script>

    <body>
        <div id="chartContainer" style="height: 300px; width: 100%;"></div>
