Getting coordinates from mouse clicks on plane

I am struggling to find a notebook that get coordinates when the user clicks with mouse in rectangular area. Any hints? Thanks.

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!
