d3.pointer(evt) returns the pointer location of evt relative to the HTML element that the event is attached to. So you might have something like:

div.on("click", function (evt) {
  let [x,y] = d3.pointer(evt);
  // Do something with  x and y

Here’s an example where the click coordinates are reported:


Thanks a lot, that solves my problem!
