The final chart appears like this:

Create a Report and Bind Report to Data

2. Under Type, select 'Json Provider'.
3. Go to the Content tab under Connection and set the type of JSON data to 'External file or URL'.
4. In the Select or type the file name or URL field, enter the following URL:

   For more information, see the JSON Provider topic.

4. Click OK to save the changes.

Create Basic Structure of Chart

We will use the Chart Wizard dialog to configure chart data values and basic customization. If you have a dataset added to your report, on Chart's drag-drop operation, the wizard appears. See the topic on Chart Wizard for more information. You can make further adjustments to the chart after you exit the wizard by accessing the properties of chart elements through dialogs, property panels, and adorners.

1. Drag-drop Chart data region onto the design area. The New Chart dialog appears with an option to select the query and the plot type.
2. Select the Query as the dataset name (Stats)  and the Plot Type as 'Polar'.
3. Click Next to configure data values.
4. Under Configure Chart Data Values, add the following value from the drop-down, set the corresponding captions, and click Next.    

   Field	Aggregate	Caption
   [SalesAmount]	Sum	Sales Amount

5. In the Configure Chart Data Groupings, set the Categories > Group By to [Sales Channel].
6. Set the Series > Group By to [Product Category].
7. Set Series > Layout Type to 'Stack'.
8. Click Next and Choose Report Colors from Theme and Style, and preview your chart.
                
   
   Now that the basic structure of your chart is ready, let us add more meaning to the chart using the properties via the Chart Panels, Adorners, and Property Panel.
