vue2使用 vis-network 和 vue-vis-network 插件封装一个公用的关联关系图

效果图：

vis组件库：vis.js

vis-network中文文档：vis-network

安装组件库：

npm install vis-network vue-vis-network
或
yarn add vis-network vue-vis-network

新建RelationGraph.vue文件：

 
<script>
	import {
		Network
	} from 'vis-network/standalone/esm/vis-network.js';
	import VueVisNetwork from 'vue-vis-network';
 
	export default {
		name:"RelationGraph",
		props: {
			nodes: {
				type: Array,
				required: true,
			},
			edges: {
				type: Array,
				required: true,
			},
			options: {
				type: Object,
				default: () => ({}),
			},
		},
		components: {
			VueVisNetwork,
		},
		mounted() {
			// 创建关联关系图
			const container = this.$refs.networkContainer;
			const data = {
				nodes: this.nodes,
				edges: this.edges,
			};
			new Network(container, data, this.options);
		},
	};
script>

页面使用：

<div>
	<relation-graph :nodes="nodes" :edges="edges" :options="graphOptions">relation-graph>
div>

import RelationGraph from './RelationGraph.vue';
export default {
        components: {
