pie-chart-js is a small JavaScript component to render a simple, plain, responsive pie chart using HTML5 canvas and Custom Element.

How to use it:

1. Load the pie-chart-js.js library at the end of your HTML document.

<script src="pie-chart-js.js"></script>

2. Add slices (pie elements) with custom values & background colors to the pie chart component. That’s it.

<pie-chart id="pieChart">
  <pchart-element name="Rent" value="11000" colour="#00A676">

3. Adjust the size of the pie chart on window resize.

  var c = document.getElementById("pieChart");
