我正在尝试使用GitHub上提供的d3js源代码来绘制WordCloud GitHub
我的index.html文件如下:
<html xmlns="html">
<head>
<title>Visualization Medley</title>
<link rel="stylesheet"
href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<link rel="stylesheet" href="medley.css">
</head>
<body>
<div class="container">
<h3>Word Cloud</h3>
<div id="world-cloud"></div>
</div>
<script type="text/javascript" src="https://d3js.org/d3.v3.min.js"/><\script>
<script type="text/javascript" src="C:/Users/xxx/Desktop/d3.layout.js"/><\script>
<script type="text/javascript" src="C:/Users/xxx/Desktop/medley.js"/>
<\script>
</body>
</html>
我的d3.layout.js文件包含以下代码:

我的medley.js源代码:

当我打开index.html文件时,它没有显示默认的wordcloud。谁能告诉我哪里出错了?
我以前没有编写JavaScript / HTML代码的经验。

以下是显示云的代码的略微修改版本:
var fill = d3.scale.category20();
var layout = d3.layout.cloud()
.size([500, 500])
.words([
"Hello", "world", "normally", "you", "want", "more", "words",
"than", "this"].map(function(d) {
return {text: d, size: 10 + Math.random() * 90, test: "haha"};
}))
.padding(5)
.rotate(function() { return ~~(Math.random() * 2) * 90; })
.font("Impact")
.fontSize(function(d) { return d.size; })
.on("end", draw);
layout.start();
function draw(words) {
d3.select("body").append("svg")
.attr("width", layout.size()[0])
.attr("height", layout.size()[1])
.append("g")
.attr("transform", "translate(" + layout.size()[0] / 2 + "," + layout.size()[1] / 2 + ")")
.selectAll("text")
.data(words)
.enter().append("text")
.style("font-size", function(d) { return d.size + "px"; })
.style("font-family", "Impact")
.style("fill", function(d, i) { return fill(i); })
.attr("text-anchor", "middle")
.attr("transform", function(d) {
return "translate(" + [d.x, d.y] + ")rotate(" + d.rotate + ")";
})
.text(function(d) { return d.text; });
}

我首先将依赖项修改为jasondavies/d3-cloud:
<script type="text/javascript" src="https://cdn.rawgit.com/jasondavies/d3-cloud/master/build/d3.layout.cloud.js"/></script>
最不可能导致图表不显示的原因是对云的调用,应该是:
var layout = d3.layout.cloud().size([500, 500]).words([...
而不是:
var layout = cloud().size([500, 500]).words([...
