如何绘制一条线来连接两个或多个视图？

<div class="container">
  <div class="view1"></div>
  <div class="view2"></div>
</div>

.container {
  position: relative;
  width: 100%;
  height: 200px;
}

.view1, .view2 {
  position: absolute;
  width: 50px;
  height: 50px;
  background-color: #f00;
}

.view1 {
  top: 50px;
  left: 50px;
}

.view2 {
  top: 100px;
  left: 200px;
}

.view1::before {
  content: "";
  position: absolute;
  top: 25px;
  left: 75px;
  width: 125px;
  height: 2px;
  background-color: #000;
}

.view2::before {
  content: "";
  position: absolute;
  top: 25px;
  left: -75px;
  width: 275px;
  height: 2px;
  background-color: #000;
}
