roughViz.js is a reusable JavaScript library for creating sketchy/hand-drawn styled charts in the browser, based on D3v5, roughjs, and handy.

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 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 |
Visit this link for interactive examples of each chart.
Apply the features of roughjs to each chart:
roughness:

fillStyle

fillWeight

As well as additional chart-specific options (see API below)
Via CDN (expose the roughViz global in html):
<script src="https://unpkg.com/rough-viz@2.0.5"></script>
Via npm:
npm install rough-viz
Want to use with React? There's a wrapper!:
npm install react-roughviz
Want to use with Vue? There's a wrapper!:
npm install vue-roughviz
Want to use it with Python? Go crazy:
pip install py-roughviz
If you're using ESM, make sure to import the library:
import roughViz from "rough-viz";
Create some container elements, one for each chart:
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,
}
);
