小鱼儿心语：不要那么敏感，也不要那么心软，太敏感和太心软的人，肯定过得不快乐，别人随便的一句话，你都要胡思乱想一整天。敏感和心软都因为太在乎别人，活不出自我，太过考虑别人的感受，注定自己不好受。
这两天做可视化页面，有这样儿一个需求，其实很简单，先上图：
围绕中心点布局.png
需要注意：复制下来可能会有接口请求报错，请根据实际情况而定
页面展示代码：
<div class="information display_flex">
<p class="title">
<img src="@/assets/img/icon3.png" />
<span>产量分布</span>
</p>
<div class="content">
// pointImg是中心的背景图片
<div class="center-point" :style="pointImg">
<span class="count">总产量</span>
<div class="countNum">
<span>{{ centerName }}</span>
<span>吨</span>
</div>
</div>
<div class="surround-box">
<ul>
<li class="circle" :style="item.circleImg" v-for="(item, index) in circles" :key="index">
<span :style="item.font">{{ item.name }}</span>
</li>
</ul>
</div>
</div>

css代码：
<style lang="scss" scoped>
//旋转
.surround-box,
.center-point {
position: absolute;
top: 23%;
left: 6%;
width: 5.8rem;
height: 3.5rem;
margin-left: -10px;
margin-top: -10px;
border-radius: 50%;
clear: both;
.count {
position: absolute;
top: 1.5rem;
left: 2.57rem;
font-size: 0.2rem;
color: #fff;
}
.countNum {
position: absolute;
top: 1.75rem;
left: 2.41rem;
width: 0.9rem;
height: 0.4rem;
color: #fff;
text-align: center;
span:nth-child(1) {
font-size: 0.32rem;
}
span:nth-child(2) {
font-size: 0.18rem;
}
}
}
.circle {
/* 这里一定要绝对定位，这样位置才能铺开来 */
position: absolute;
top: 1.4rem;
left: 2.55rem;
width: 0.75rem;
height: 0.7rem;
line-height: 0.2rem;
border-radius: 50%;
text-align: center;
color: #fff;
padding: 0.15rem 0.1rem;
cursor: pointer;
}
</style>
其实这些方法网上百度一大堆，我只是想把我亲自实践过得东西给大家分享出来，我这里用的是循环渲染，因为毕竟不是死数据，接口返回的数据格式，希望能帮助到大家~
