[SOLVED] Fusion Charts - Gantt Chart - Chart Type is not supported

I am trying the trial version of Fusion Charts. I downloaded FusionCharts XT(v3.2.2) SR5 and FusionWidgets XT (v3.2) Service Release 2 trial versions, copied the scripts and flash files into my application, included FusionCharts/jquery.min.js, FusionCharts/FusionCharts.js, FusionCharts/FusionCharts.HC.js, FusionCharts/FusionCharts.HC.Widgets.js in my aspx, I tried the below chart (Column3D) with sample JSON provided and it worked fine. i was able to see the chart.

var myChart = new FusionCharts("Column3D", "myChartId", "400", "300");
myChart.setJSONData(
{ "chart":
{ "caption": "Weekly Sales Summary", "xAxisName": "Week", "yAxisName": "Sales", "numberPrefix": "$" },
"data":
[{ "label": "Week 1", "value": "14400" },
{ "label": "Week 2", "value": "19600" },
{ "label": "Week 3", "value": "24000" },
{ "label": "Week 4", "value": "15700"}]
});
myChart.render("chartContainer");

But when i want to try gantt chart with sample JSON provided, I get Chart type not supported. Please see the code and complete JSON i tried below.

var myChart = new FusionCharts("Gantt", "myChartId", "800", "700");
myChart.setJSONData(

I dont think there is any problem with the JSON asi took it straight from the sample. But why am i getting Chart type not supported? Is there anything additional we have to do to make fusionwidgets work? Any help would be appreciated.
