It's working perfectly without defining any width and height.
The goal is to display the graph about 1/3 the original size. Using this code
this._recrutingFunnel = new FunnelGraph({
container: '#funnel',
direction: 'vertical',
gradientDirection: 'vertical',
height: 133,
width: 100,
data: this._data,
displayPercent: true
})
