How to invoke a callback at the end of a transition with D3 and JavaScript?

For instance, we write

d3.select("#myid").transition().style("opacity", "0").on("end", myCallback);

to select the element with d3.select.

Then we call transition and style to add a transition to set opacity of the element to 0.

Next, we call on with 'end' and a callback function that runs when the end event is emitted.

Then end event is emitted when the transition is done.
