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

Visit this link for interactive examples of each chart.

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-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

How 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,
  }
);
