roughViz.js is a reusable JavaScript library for creating sketchy/hand-drawn styled charts in the browser, based on D3v5, roughjs, and handy.
Why?
Use these charts where the communication goal is to show intent or generality, and not absolute precision. Or just because they're fun and look weird.
Chart Types
| Chart Type | API |
|---|---|
| Bar | roughViz.Bar |
| Horizontal Bar | roughViz.BarH |
| Donut | roughViz.Donut |
| Line | roughViz.Line |
| Pie | roughViz.Pie |
| Scatter | roughViz.Scatter |
| Stacked Bar | roughViz.StackedBar |

Features
Apply the features of roughjs to each chart:
roughness:
fillStyle
fillWeight
As well as additional chart-specific options (see API below)
Installation
Via CDN (expose the roughViz global in html):
<script src="https://unpkg.com/rough-viz@2.0.5"></script>Via npm:
npm install rough-vizWant to use with React? There's a wrapper!:
npm install react-roughvizWant to use with Vue? There's a wrapper!:
npm install vue-roughvizWant to use it with Python? Go crazy:
pip install py-roughvizHow to use
If you're using ESM, make sure to import the library:
import roughViz from "rough-viz";
Create some container elements, one for each chart:
<!--you can name each id whatever you want -->
<div id="viz0"></div>
<div id="viz1"></div>In the javascript, just create charts, referencing the desired container:
// create Bar chart from csv file, using default options
new roughViz.Bar({
element: '#viz0', // container selection
data: 'https://raw.githubusercontent.com/jwilber/random_data/master/flavors.csv',
labels: 'flavor',
values: 'price'
});
// create Donut chart using defined data & customize plot options
new roughViz.Donut(
{
element: '#viz1',
data: {
labels: ['North', 'South', 'East', 'West'],
values: [10, 5, 8, 3]
},
title: "Regions",
width: window.innerWidth / 4,
roughness: 8,
colors: ['red', 'orange', 'blue', 'skyblue'],
stroke: 'black',
strokeWidth: 3,
fillStyle: 'cross-hatch',
fillWeight: 3.5,
}
