A word cloud react component built with d3-cloud.
npm install react-d3-cloud
Simple:
import React from 'react';
import { render } from 'react-dom';
import WordCloud from 'react-d3-cloud';
const data = [
{ text: 'Hey', value: 1000 },
{ text: 'lol', value: 200 },
{ text: 'first impression', value: 800 },
{ text: 'very cool', value: 1000000 },
{ text: 'duck', value: 10 },
];
render(<WordCloud data={data} />, document.getElementById('root'));
More configuration:
import React from 'react';
import { render } from 'react-dom';
import WordCloud from 'react-d3-cloud';
import { scaleOrdinal } from 'd3-scale';
import { schemeCategory10 } from 'd3-scale-chromatic';
const data = [
{ text: 'Hey', value: 1000 },
{ text: 'lol', value: 200 },
{ text: 'first impression', value: 800 },
{ text: 'very cool', value: 1000000 },
{ text: 'duck', value: 10 },
];
const schemeCategory10ScaleOrdinal = scaleOrdinal(schemeCategory10);
render(
<WordCloud

width={500}
height={500}
font="Times"
fontStyle="italic"
fontWeight="bold"
fontSize={(word) => Math.log2(word.value) * 5}
spiral="rectangular"
rotate={(word) => word.value % 360}
padding={5}
random={Math.random}
fill={(d, i) => schemeCategory10ScaleOrdinal(i)}
onWordClick={(event, d) => {
console.log(`onWordClick: ${d.text}`);
}}
onWordMouseOver={(event, d) => {
console.log(`onWordMouseOver: ${d.text}`);
}}

for more detailed props, please refer to below:
name | description | type | required | default |
---|---|---|---|---|
data | The words array | { text: string, value: number }>[] |
โ | |
width | Width of the layout (px) | number |
700 |
|
height | Height of the layout (px) | number |
600 |
|
font | The font accessor function, which indicates the font face for each word. A constant may be specified instead of a function. | string | (d) => string |
'serif' |
|
fontStyle | The fontStyle accessor function, which indicates the font style for each word. A constant may be specified instead of a function. | string | (d) => string |
'normal' |
|
fontWeight | The fontWeight accessor function, which indicates the font weight for each word. A constant may be specified instead of a function. | string | number | (d) => string | number |
'normal' |
|
fontSize | The fontSize accessor function, which indicates the numerical font size for each word. | (d) => number |
(d) => Math.sqrt(d.value) |
|
rotate | The rotate accessor function, which indicates the rotation angle (in degrees) for each word. | (d) => number |
() => (~~(Math.random() * 6) - 3) * 30 |
|
spiral | The current type of spiral used for positioning words. This can either be one of the two built-in spirals, "archimedean" and "rectangular", or an arbitrary spiral generator can be used | 'archimedean' | 'rectangular' | ([width, height]) => t => [x, y] |
'archimedean' |
|
padding | The padding accessor function, which indicates the numerical padding for each word. | number | (d) => number |
1 |
|
random | The internal random number generator, used for selecting the initial position of each word, and the clockwise/counterclockwise direction of the spiral for each word. This should return a number in the range [0, 1) . |
(d) => number |
Math.random |
|
fill | The fill accessor function, which indicates the color for each word. | (d, i) => string |
(d, i) => schemeCategory10ScaleOrdinal(i) |
|
onWordClick | The function will be called when click event is triggered on a word |
(event, d) => {} |
null | |
onWordMouseOver | The function will be called when mouseover event is triggered on a word |
(event, d) => {} |
null | |
onWordMouseOut | The function will be called when mouseout event is triggered on a word |
(event, d) => {} |
null |
To make <WordCloud />
work with Server-Side Rendering (SSR), you need to avoid rendering it on the server:
{
typeof window !== 'undefined' && <WordCloud data={data} />;
}
As of version 0.10.1, <WordCloud />
has been wrapped by React.memo()
and deep equal comparison under the hood to avoid unnecessary re-render. All you need to do is to make your function props deep equal comparable using useCallback()
:
import React, { useCallback } from 'react';
import { render } from 'react-dom';
import WordCloud from 'react-d3-cloud';
import { scaleOrdinal } from 'd3-scale';
import { schemeCategory10 } from 'd3-scale-chromatic';
function App() {
const data = [
{ text: 'Hey', value: 1000 },
{ text: 'lol', value: 200 },
{ text: 'first impression', value: 800 },
{ text: 'very cool', value: 1000000 },
{ text: 'duck', value: 10 },
];
const fontSize = useCallback((word) => Math.log2(word.value) * 5, []);
const rotate = useCallback((word) => word.value % 360, []);
const fill = useCallback((d, i) => scaleOrdinal(schemeCategory10)(i), []);
const onWordClick = useCallback((word) => {
console.log(`onWordClick: ${word}`);
}, []);
const onWordMouseOver = useCallback((word) => {
console.log(`onWordMouseOver: ${word}`);
}, []);
const onWordMouseOut = useCallback((word) => {
console.log(`onWordMouseOut: ${word}`);
}, []);
return (
<WordCloud
data={data}
width={500}
height={500}
font="Times"
fontStyle="italic"
fontWeight="bold"
fontSize={fontSize}
spiral="rectangular"
rotate={rotate}
padding={5}
random={Math.random}
fill={fill}
onWordClick={onWordClick}
onWordMouseOver={onWordMouseOver}
onWordMouseOut={onWordMouseOut}
/>
);
);
