How to make a pie chart in CSS

I saw some people opting for Google Developers Tool, its very tough and it also uses JS and you only want CSS. So here is the most easy way, Pure CSS, made by using background gradient.

.pie {
  width: 400px;
  height: 400px;
  background-image: conic-gradient(orange 64%, blue 17%, black);
  border-radius: 50%
}

<div class="pie"></div>
