You can change the specificChart id to any unique value. This allows you to target multiple donuts on the same page and to give them unique colors.

<div id="specificChart" class="donut-size">
  <div class="pie-wrapper">
    <span class="label">
        <span class="num">0</span><span class="smaller">%</span>
    <div class="pie">
      <div class="left-side half-circle"></div>
      <div class="right-side half-circle"></div>
    <div class="shadow"></div>


This is completely customizable, but the main controls are right at the top in the variables.

This is the function that lets you update the values. It accepts selector for which donut chart to update, a number value for the percent, and a boolean for Donut or Pie chart.

 * Also allows you to set if it is a donut or pie chart
 * @param  {string}  el      The selector for the donut to update. '#thing'
 * @param  {number}  percent Passing in 22.3 will make the chart show 22%
 * @param  {boolean} donut   True shows donut, false shows pie
function updateDonutChart (el, percent, donut) {
    percent = Math.round(percent);
    if (percent > 100) {
        percent = 100;
    } else if (percent < 0) {
        percent = 0;
    var deg = Math.round(360 * (percent / 100));

    if (percent > 50) {
        $(el + ' .pie').css('clip', 'rect(auto, auto, auto, auto)');
        $(el + ' .right-side').css('transform', 'rotate(180deg)');
    } else {
        $(el + ' .pie').css('clip', 'rect(0, 1em, 1em, 0.5em)');
