## Usage
see [Examples](https://www.sgratzl.com/chartjs-chart-wordcloud/examples/)
or at this [![Open in CodePen][codepen]](https://codepen.io/sgratzl/pen/WNwzYgy)
## Word Cloud
### Data Structure
```ts
const config = {
type: 'wordCloud',
data: {
// text
labels: ['Hello', 'world', 'normally', 'you', 'want', 'more', 'words', 'than', 'this'],
datasets: [
{
label: 'DS',
// size in pixel
data: [90, 80, 70, 60, 50, 40, 30, 20, 10],
},
],
},
options: {},
};
```
### Styling of elements
A word has the basic FontSpec styling options (family, color, ...). In addition it has several options regarding rotating the text.
Controller options:
https://github.com/sgratzl/chartjs-chart-wordcloud/blob/14ac8327c2209c0d8f89fdd6cd86d2b2d7daedce/src/controllers/WordCloudController.ts#L184-L193
Word element options:
https://github.com/sgratzl/chartjs-chart-wordcloud/blob/14ac8327c2209c0d8f89fdd6cd86d2b2d7daedce/src/elements/WordElement.ts#L3-L29
## ESM and Tree Shaking
The ESM build of the library supports tree shaking thus having no side effects. As a consequence the chart.js library won't be automatically manipulated nor new controllers automatically registered. One has to manually import and register them.
Variant A:
```js
import { Chart } from 'chart.js';
import { WordCloudController, WordElement } from 'chartjs-chart-wordcloud';
Chart.register(WordCloudController, WordElement);
...
new Chart(ctx, {
type: WordCloudController.id,
data: [...],
});
```
Variant B:
```js
import { WordCloudChart } from 'chartjs-chart-wordcloud';
new WordCloudChart(ctx, {
data: [...],
});
```
## Development Environment
```sh
npm i -g yarn
yarn install
yarn sdks vscode
```
### Common commands
```sh
yarn compile
yarn test
yarn lint
yarn fix
yarn build
yarn docs
