mysql - 未定义ReferenceError和d3plus

我正在尝试查询MySQL数据库并使用d3plus创建可视化。我的后端是Express.JS，模板是EJS

这是我的错误：

ReferenceError: C:\cit\views\results.ejs:10
    8|

    9| <script>

 >> 10| <%   var data = [

    11|      {"year": 2011, "name":"jobs", "value": "2011"}

    12|    ]

    13|    var visualization = d3plus.viz()


d3plus is not defined

    at Query.<anonymous> (C:\cit\node_modules\mysql\lib\Connection.js:502:10)

我的results.ejs代码：

<% include partials/header.ejs %>
 <h1>= <%= naics %></h1>
 <h1>= <%= industry %></h1>

<div id="viz"></div>

<script>
<% var data = [
     {"year": 2011, "name":"jobs", "value": "2011"}
   ]
   var visualization = d3plus.viz()
   .container("#viz")
    .data(data)
    .type("bar")
    .id("name")
    .x("year")
    .y("value")
    .draw() %>
 </script>

 <% include partials/footer.ejs %>

还有我的具有d3plus脚本源的header.ejs代码：

<!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8">
  <script src="http://d3plus.org/js/d3.js"></script>
  <script src="http://d3plus.org/js/d3plus.js"></script>
  <title>The HTML5 Herald</title>
  <meta name="description" content="The HTML5 Herald">
  <meta name="author" content="SitePoint">

</head>

<body>

现在，我正在制作可视化的硬拷贝，但仍然遇到问题。可能是什么问题？

PS：我的脚注中也添加了脚本源。万一这是问题。不是。

最佳答案

我认为您正在使用d3plus v1。相反，您必须使用d3plus v2。

new d3plus.BarChart() .select("#viz") .data(data) .x("year") .y("value") .groupBy("name") .render();

D3plus
