# Chart

## Usage

```jsx
// import the component
import ElementChart from 'calypso/my-sites/chart';

// And use it inline inside the render method of another component
function render() {
	return (
		<ElementChart
			loading={ loading /*boolean*/ }
			data={ data /*array*/ }
			barClick={ barClick /*function*/ }
		/>
	);
}

// Example Data Array
/*
[ {
	'label': 		<String>, // x-axis label
	'value': 		<Number>, // bar value
	'nestedValue':	<Number>, // nested bar value or null if no nested bar
