   以下示例代码，我想自定义 formatter， 格式为： "xxx - > vvv -> ccc"
   
   ```js
   myChart.showLoading();
   $.get('data/asset/data/flare.json', function (data) {
       myChart.hideLoading();
   
       myChart.setOption(option = {
           tooltip: {
               trigger: 'item',
               triggerOn: 'mousemove',
               formatter:'{b0}'
           },
           series: [
               {
                   type: 'tree',
                   data: [data],
                   top: '18%',
                   bottom: '14%',
                   layout: 'radial',
                   symbol: 'emptyCircle',
                   symbolSize: 7,
                   initialTreeDepth: 3,
                   animationDurationUpdate: 750
               }
           ]
       });
   });
   ```
