如下图所示，在浏览器直接打开，，在chrome中测试上面的代码，控制台会报如下错误：
d3.v4.min.js:2 Access to XMLHttpRequest at 'file:///C:/Users/volod/Desktop/D3.js%E5%8A%A0%E8%BD%BDcsv%E6%95%B0%E6%8D%AE/nemployment.tsv' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
这是因为安全机制禁止了cross origin request，不允许直接读取本地文件, 所以我们需要一个webserver来server我们的数据
<1>在扩展中搜索插件 Debugger for Chrome 进行安装。
<2>配置launch.json文件，根据步骤来。file就是你在浏览器中需要运行的文件的路径。
{ // 使用 IntelliSense 了解相关属性。 // 悬停以查看现有属性的描述。 // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "type": "chrome", "request": "launch", "name": "Launch Chrome against localhost", "url": "http://localhost:8080", "webRoot": "${workspaceFolder}" } ] }
<3>配置好之后，直接使用调试是不行的，需要开启服务器。
3. npm install -g live-server安装，开启服务器
（3与4都能实现VS Code在本地进行调试和打开本地服务器，选择其中一种方法即可）
1.打开vs code制台。选择终端，在终端里输入 npm install -g live-server 进行安装.
npm install -g live-server
2.然后再输入live-server,按下回车，如下图所示：
4.在vs code中安装live server 插件
（3与4都能实现VS Code在本地进行调试和打开本地服务器，选择其中一种方法即可），如下图所示：
5.以下是使用D3 v4实现下图效果：
