• ForcedDirectedTree: new zoom-related methods: zoomToPoint(point, level, center) and zoomToDataItem(dataItem, level, center).
• New global function: am4core.createDeferred(callback, scope, ...parameters). Can be used to create multiple charts in a truly safe daisy-chain (next chart starts to be instantiated only when previous triggers a ready event). Returns a Promise with chart instance.
