xiashuyuan commented on issue #8597: 关系图 data 的 name 属性不允许重复，会报错。

   已解决：
   1. 保持 data 中name不重复，用 value 或其他字段名称表示要展示的节点名称；
   2. 使用 label.formatter 输出节点名称；
   3. links 中 source 和 target 用数据项的索引值。
   
   option = {
   label:{
                   show: true,
                   formatter: function(value){
                       return value.data.value;
                   }
               },
               data: [{
                   // name: '节点1',
                   a: '`1',
                   value: 10,
                   x: 300,
                   y: 300,
               }, {
                   // name: '节点2',
                   value: 20,
                   x: 800,
                   y: 300
               }, {
                   // name: '节点3',
                   value: 10,
                   x: 550,
                   y: 100
               }, {
                   // name: '节点4',
                   value: 30,
                   x: 550,
                   y: 500
               }, {
                   name: '节点4',
                   value: 10,
                   x: 550,
                   y: 500
               }],
               // links: [],
               links: [{
                   source: 0,
                   target: 1,
                   symbolSize: [5, 20],
                   label: {
                       normal: {
                           show: true
                       }
                   },
                   lineStyle: {
                       normal: {
                           width: 5,
                           curveness: 0.2
                       }
                   }
               }],
   };
