How to remove a parent element in D3.js once the child transition has completed

How can I use D3.js to animate a child element and then remove the parent element at the end of the animation?

  1. Is there a way to know when the transition on the child element has finished?
  2. In jQuery, you would do $(this).parent().remove(); to remove the parent element. How would I achieve this in D3 syntax?

    li.enter() .append('li') .append('i') .text(function (d) { return d; });

    li.exit() .selectAll('i') .transition() .style('opacity', 0) .remove(); // Need to remove parent element here...

  1. What is the best way to know when a child transition has ended?

Through my exploration on the topic, I discovered this helpful resource: Invoke a callback at the end of a transition. It led me to understand that utilizing transition.each([type],listener) function can be useful, such as in the example below: d3.selectAll('i').transition().each('end', function () { ... }); This code snippet allows for triggering a callback at the 'end' event of each element's transition.

  1. Is there an equivalent way to remove the parent element like in jQuery $(this).parent().remove();?

I found success using the following syntax:

d3.select(this.parentNode).transition().style('opacity', 0).remove();
