??可控進度百分比

 plan: 88

也可以通過設置繪線類型，改變樣式

svg ellipse {
  //設置為圓角
  stroke-linecap: round;
}

代碼如下：

<template>
  <div class="overall">
    <div class="box">
      <svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
        <ellipse
          class="bck"
          ry="94.5"
          rx="94.5"
          cy="99.95313"
          cx="100"
          stroke-width="6"
          stroke="#ccc"
          fill="none"
        />
        <ellipse
          class="line"
          ry="94.5"
          rx="94.5"
          cy="99.95313"
          cx="100"
          stroke-width="6"
