页面的head部分，引入jQuery库，并设置好页面各元素的样式，代码如下：

<script type="text/javascript" src="js/jquery.min.js"></script>
<style type="text/css">
body {
  font-family: 'Microsoft YaHei','Lantinghei SC','Open Sans',Arial,'Hiragino Sans GB','STHeiti','WenQuanYi Micro Hei','SimSun',sans-serif;
  background: #EEE;

  text-align: center;
}
body * {
  font-weight: 300;
  margin: 0;
  padding: 0;
}

h1, h2 {
  text-transform: uppercase;
}

@-webkit-keyframes bake-pie {

}
</style>

页面的body部分，用多个li标签来放入预设的相关统计数据，代码如下：

<div class="wrapper">
  <h1>会员状态统计</h1>
  <div class="pie-charts">
    <div class="pieID--operations pie-chart--wrapper">
      <h2>兴趣</h2>
      <div class="pie-chart">
        <div class="pie-chart__pie"></div>
        <ul class="pie-chart__legend">

    <div class="pieID--region pie-chart--wrapper">
      <h2>区域</h2>
      <div class="pie-chart">

        </ul>
      </div>
    </div>
  </div>
</div>

页面的底部，通过javascript来结合数据生成统计图表，代码如下：

<script type="text/javascript">
function sliceSize(dataNum, dataTotal) {
  return (dataNum / dataTotal) * 360;
}

function addSlice(id, sliceSize, pieElement, offset, sliceID, color) {
  $(pieElement).append("<div class='slice "+ sliceID + "'><span></span></div>");
  var offset = offset - 1;
  var sizeRotation = -179 + sliceSize;

  $(id + " ." + sliceID).css({
    "transform": "rotate(" + offset + "deg) translate3d(0,0,0)"
  });

  $(id + " ." + sliceID + " span").css({
    "transform"       : "rotate(" + sizeRotation + "deg) translate3d(0,0,0)",
    "background-color": color
  });
}

function iterateSlices(id, sliceSize, pieElement, offset, dataCount, sliceCount, color) {
  var
    maxSize = 179,
    sliceID = "s" + dataCount + "-" + sliceCount;

  if( sliceSize <= maxSize ) {
    addSlice(id, sliceSize, pieElement, offset, sliceID, color);
  } else {
    addSlice(id, maxSize, pieElement, offset, sliceID, color);
    iterateSlices(id, sliceSize-maxSize, pieElement, offset+maxSize, dataCount, sliceCount+1, color);
  }
}

function createPie(id) {
  var
    listData      = [],
    listTotal     = 0,
    offset        = 0,
    i             = 0,
    pieElement    = id + " .pie-chart__pie"
    dataElement   = id + " .pie-chart__legend"

    color         = [

      "rgb(2,166,209)",
      "rgb(5,116,206)",

  color = shuffle( color );

  $(dataElement+" span").each(function() {
    listData.push(Number($(this).html()));
  });

  for(i = 0; i < listData.length; i++) {
    listTotal += listData[i];
  }

  for(i=0; i < listData.length; i++) {
    var size = sliceSize(listData[i], listTotal);
    iterateSlices(id, size, pieElement, offset, i, 0, color[i]);
    $(dataElement + " li:nth-child(" + (i + 1) + ")").css("border-color", color[i]);
    offset += size;
  }
}

function shuffle(a) {
    var j, x, i;
    for (i = a.length; i; i--) {
        j = Math.floor(Math.random() * i);
        x = a[i - 1];
        a[i - 1] = a[j];
        a[j] = x;
    }

    return a;
}

function createPieCharts() {
  createPie('.pieID--region' );
  createPie('.pieID--operations' );
}

createPieCharts();
