how to hook events on graphics layer at 4.6

BanchanaPandey

With 4.6 version of JSAPI, many events that we could hook into for the GraphicsLayer and many other things like Map,etc have gone away. How can we tap into and event when graphics are added to a graphicslayer on a map or how can we implement something like this pulsing graphics layer - JSFiddle in 4.6 since similar events on Map are no more available and MapView doesn't offer anything like that.
