 import RelationGraph from 'relation-graph'
 export default {
   name: 'Demo',
   components: { RelationGraph },
   data() {
     return {
       graphOptions: {
         allowSwitchLineShape: true,
         allowSwitchJunctionPoint: true,
         defaultJunctionPoint: 'border'
         // 这里可以参考"Graph 图谱"中的参数进行设置:http://relation-graph.com/#/docs/graph
       }
     }
   },
   mounted() {
     this.showSeeksGraph()
   },
   methods: {
     showSeeksGraph() {
       var __graph_json_data = {
         rootId: 'a',
         nodes: [
            // node配置选项：http://relation-graph.com/#/docs/node
            // node支持通过插槽slot完全自定义，示例：http://relation-graph.com/#/demo/adv-slot
