iamjared v2.0.4

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

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.

Features

Chart Types (more to come!)

Apply the features of roughjs to each chart:

roughness:

fillStyle

fillWeight

As well as additional chart-specific options (see API below)

Customize (same data, different charts)

Installation

Via CDN (expose the roughViz global in html):

<script src="https://unpkg.com/rough-viz@1.0.2"></script>

Via npm:

npm install rough-viz

How to use

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 donut chart from csv file, using default options
 new roughViz.Bar({
    element: '#vis0', // 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: '#vis1',
    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,
  }
