        myChart.setOption(option);
    </script>
</body>
</html>

显示效果如下：

解释：

  1.  设置网页标题：
    1. <title>QQ部星座分布图</title>
  2. 导入在线的echarts库：
    1. <script src="http://echarts.baidu.com/dist/echarts.js"></script>
  3. 设置页面尺寸：
    1. <div id="main" style="width:800px;height:800px"></div>
  4. 初始化echarts实例：
    1. var myChart = echarts.init(document.getElementById('main'));
  5. 设置图表内容：
    1. var option = {}
  6. 在echarts实例中载入option：
    1. myChart.setOption(option);
  7. 对option的解释
    1. 包含了一个tooltip——用于动态显示数据标签，和三个series，series的类型为“pie”饼图。
    2. tooltip的显示格式为：formatter: "{a} <br/>{b}: {c} ({d}%)"，即显示数字和百分比。
    3. radius用于设置饼图的内外范围，如：radius: ['75%', '96%']。
    4. 接下来设置标签的文本格式和数据内容即可。
