How does front-end Vue dynamically display organizational structure level chart based on back-end data?

Front-end Vue dynamic organizational structure diagram implementation solution

This article discusses how to use back-end data to dynamically generate organizational structure charts in the Vue.js framework, similar to the figure below:

(This should be replaced with the actual picture)

This is crucial in enterprise applications, requiring efficient and aesthetic presentation of complex hierarchical relationships and personnel structures, and supporting real-time updates.

Solution:

It is recommended to use the AntV X6 library to implement it. AntV X6 is a powerful graphics library that can easily handle complex graphics display needs, including drawing organizational diagrams. It provides rich APIs and examples to facilitate developers to quickly build and customize graphics.

Implementation steps:

1. Data preparation: The backend should return structured JSON data, for example:

 [
  {
    "id": 1,
    "name": "CEO",
    "children": [
      { "id": 2, "name": "VP1", "children": [{ "id": 4, "name": "Manager1" }] },
      { "id": 3, "name": "VP2", "children": [{ "id": 5, "name": "Manager2" }, { "id": 6, "name": "Manager3" }] }
    ]
  }
]

2. AntV X6 Integration: Install AntV X6 in Vue project:

 npm install @antv/x6

3. Component development: Create a Vue component, and use the AntV X6 API to dynamically create nodes and edges based on the received data. The core logic is to recursively traverse JSON data, create nodes, and establish parent-child relationships based on children attributes. You can use x6.graph.addNode() and x6.graph.addEdge() methods. The node style and layout can be customized according to your needs.

4. Data update: When the backend data changes, update the data in the Vue component, and AntV X6 will automatically re-render the graphics to achieve real-time updates.

5. Style Customization: AntV X6 allows highly customization of node styles, edge styles, and layouts to meet different visual needs. You can refer to the documentation and examples of AntV X6 for adjustments.

Sample code snippet (simplified version):

<template>
  <div id="container"></div>
</template>

<script>
import { Graph } from '@antv/x6';

export default {
  data() {
    return {
      graphData: [] // 后端返回的数据
    };
  },
  mounted() {
    this.initGraph();
  },
  methods: {
    initGraph() {
      const graph = new Graph({
        container: document.getElementById('container'),
        // ...其他配置
      });

      // 递归函数，创建节点和边
      const createNodesAndEdges = (data) => {
        // ...
      };

      createNodesAndEdges(this.graphData);
    }
  }
};
</script>

It should be noted that the above is just a simplified example, and the actual implementation needs to deal with more details, such as error processing, data format conversion, more complex layout algorithms, etc. It is recommended to refer to the official documentation and examples of AntV X6 to learn how to use its API for more complex graphical operations and customization. This will ensure that your organizational chart is both efficient and beautiful.
