Usage

let chart = new D3ForceGraph(container, data, config)

Example:

`javascript
import {D3ForceGraph} from 'd3-force-graph'

let $container = document.getElementById('container')
let testData = {
nodes: [{
id: 'TestNodeA'
}, {
id: 'TestNodeB'
}],
links: [{
source: 'TestNodeA',
target: 'TestNodeB'
}]
}
let chart = new D3ForceGraph($container, testData, {
width: 500,
height: 500
})
`
