Simple Pie
🥧 🍩

Super light weight (4.4kb) and super simple svg pie/doughnut diagram

This project creates simple svg pie and doughnut charts for infographics like graphs and others.

Note: If you are going to use simple diagram in react project, please check React Simple Pie out.
simple-pie and react-simple-pie packages are parts of the Simple Pie Project repo

Check out the demo here


Some time ago I had to integrate a network graph. And the every node of the network graph would be tiny pie chart. The network graph library doesn't support anything else except png or svg as node inner content. So, it is not very nice idea to keep a bunch of png or svg files for every case of data distribution. And for obvious reasons it is not possible to use HighCharts, Chart.js or other data visualization library. (Perhaps it would work with d3, but I'm not sure, it is an overkill to keep such big library for the such small purpose)

Well the simple-pie does exactly this thing. It generates tiny svg pie which can be integrated into network graph or map or any other case, when you can't use data-visualization libraries.

net and map cases


npm install simple-pie --save


yarn add simple-pie



import {simplePie, simpleDoughnut} from "simple-pie";

const svgPie = simplePie([2, 1, 1, 2]);
const svgDoughnut = simpleDoughnut([2, 1, 1, 2]);


<div id="pie-container"></div>
<div id="doughnut-container"></div>

<script src="node_modules/simple-pie/dist/simple-pie.min.js"></script>
    const svgPieElement = simplePie([2, 1, 1, 2]);

    const svgDoughnutElement = simpleDoughnut([2, 1, 1, 2]);

Since simplePie and simpleDoughnut return regular svg, you can use it as you wish.

Note: svg height and width are 100%, so it trys to extend itself to available space. Thus, you should have wrapper with dimensions for your simple-pie diagram.


// Pie
type TPieOptions = {
  pallet?: string[];
  borderColor?: string;
  borderWidth?: number;

function simplePie(
  values: number[],
  options?: TPieOptions
): SVGElement;

// Doughnut
type TDoughnutOptions = TPieOptions & {
  inner?: number;                         // 0..1 - percent from outer radius

function simpleDoughnut(
  values: number[],
  options: TDoughnutOptions = {}
): SVGElement

If you need borderless diagram, just set borderColor: "transparent" or borderWidth: 0

Old version interface

The old version of pie diagram is still supported. However, it is deprecated. Please use the new one.

export function simplePie(
  values: number[],
  pallet?: string[],
  borderColor?: string,
  borderWidth?: number
): SVGElement;

simpleDoughnut has only new version of the interface
