我目前正在尝试在开始输入自己的数据/对其进行编辑之前，在浏览器上从d3pie运行示例代码。当我将其粘贴到JS Bin（无论是在Firefox还是Chrome上）时，都可以正常工作。代码如下所示：
<html>
<head></head>
<body>
<div id="pieChart"></div>
<script src="//cdnjs.cloudflare.com/ajax/libs/d3/3.4.4/d3.min.js"></script>
<script src="https://rawgit.com/benkeen/d3pie/master/d3pie/d3pie.min.js"> </script>
<script>
var randomval = 50;
var pie = new d3pie("pieChart", {
"header": {
"title": {
"text": "Lots of Programming Languages",
"fontSize": 24,
"font": "open sans"
},
"subtitle": {
"text": "A full pie chart to show off label collision detection and resolution.",
"color": "#999999",
"fontSize": 12,
"font": "open sans"
},
"titleSubtitlePadding": 9
},
"footer": {
"color": "#999999",
"fontSize": 10,
"font": "open sans",
"location": "bottom-left"
},
"size": {
"canvasWidth": 590,
"pieOuterRadius": "90%"
},
"data": {
"sortOrder": "value-desc",
"content": [
{
"label": "JavaScript",
"value": randomval,
"color": "#2484c1"
},
{
"label": "Ruby",
"value": 218812,
"color": "#0c6197"
},
{
"label": "Java",
"value": 157618,
"color": "#4daa4b"
}
]
},
"labels": {
"outer": {
"pieDistance": 32
},
"inner": {
"hideWhenLessThanPercentage": 3
},
"mainLabel": {
"fontSize": 11
},
"percentage": {
"color": "#ffffff",
"decimalPlaces": 0
},
"value": {
"color": "#adadad",
"fontSize": 11
},
"lines": {
"enabled": true
},
"truncation": {
"enabled": true
}
},
"effects": {
"pullOutSegmentOnClick": {
"effect": "linear",
"speed": 400,
"size": 8
}
},
"misc": {
"gradient": {
"enabled": true,
"percentage": 100
}
}
});
</script>
</body>
</html>
但是，当我复制此代码并将其粘贴到HTML文件中并在Chrome或Firefox上运行该HTML文件时，看不到任何图表！我将d3pie.min.js的脚本更改为：
<script src="d3pie.min.js></script>
并肯定我已经在本地正确保存了d3pie.min.js文件。我似乎无法弄清楚问题出在哪里，以及为什么它无法在浏览器上正确显示。过去有人遇到过这种问题吗？谢谢！
最佳答案
更改

至
