下载les-miserables.json到本地graph.html相同目录

 https://echarts.apache.org/examples/data/asset/data/les-miserables.json

graph.html代码如下

将les-miserables.json和graph.html上传到git page
查看远程效果(https://xxx/graph.html)和本地效果(file:///C:/xxx/graph.html)
本地调试，修改为如下

   <script type="text/javascript">
    var dom = document.getElementById('container');
    var myChart = echarts.init(dom, null, {
      renderer: 'canvas',
      useDirtyRect: false
    });
    var app = {};
    // var ROOT_PATH = 'https://echarts.apache.org/examples';
    // var ROOT_PATH = 'https://dogleftover.github.io/blog-beautify';
    var option;
 
    // myChart.showLoading();
// $.getJSON(ROOT_PATH + '/data/asset/data/les-miserables.json', function (graph) {
$.getJSON('les-miserables.json', function (graph) {
  console.log(graph);
  // myChart.hideLoading();
  graph.nodes.forEach(function (node) {
    node.label = {
      show: node.symbolSize > 30
    };
  });

报错如下
解决方案，参考
右键桌面的chrome图标，属性，目标，添加如下

  --allow-file-access-from-files --enable-file-cookies
 
# 完整如下
C:\Users\ychen\AppData\Local\Google\Chrome\Application\chrome.exe --allow-file-access-from-files --enable-file-cookies
# 之后打开chrome浏览器，将graph.html拖进浏览器，可以成功读取到json文件内容

les-miserables.json自定义

 {
    "nodes": [
        {
            "id": "0",  // 唯一id
            "name": "Myriel",    // 名称
            "symbolSize": 19.12381,    // 大小
            "x": -266.82776,    // 位置

            "value": 28.685715,    // 值
            "category": 0    // 所属分类
        } 
    ],
    "links": [  // 连接线
        {
            "source": "1",  // id为1的指向id为0的
