Line Chart

I can't get the ajax line chart to render in the browser. 

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager><asp:LineChart ID="LineChart1" runat="server" ChartHeight="250" ChartTitle="Chart Title" ChartWidth="400" CategoriesAxis="1,2,3,4,5,6"><Series><asp:LineChartSeries Data="3,7,2,7,5,1" LineColor="Blue" Name="Series#1" /></Series></asp:LineChart>
