Enlarge svg group element on mouseenter (D3)

this one helps. Some confusion on the question but as you said I expect the 'zoom-like' behavior here is how to achieve it...
To increase the size of the node on mouse over just add the scale to the node. Set the scale to 2 on mouseOver and on mouseOut set the scale back to 1.
code :
 var nodeEnter = node.enter().append('svg:g')
      .attr('class', 'node')
      .attr('transform', function(d) {
        return "translate(" + d.x + "," + d.y + ")";
      })
      .attr('filter', 'url(#drop-shadow)')
      .on('mouseover', function(d){d.scale = 2;tick();})
      .on('mouseout', function(d){d.scale = 1;tick();})
      .on('click', click)
      .call(force.drag);
  function nodeTransform(d) {
    if (!d.scale)
      d.scale=1;
    d.x =  Math.max(maxNodeSize, Math.min(width - (d.imgwidth / 2 || 16), d.x));
    d.y =  Math.max(maxNodeSize, Math.min(height - (d.imgheight / 2 || 16), d.y));
    return "translate(" + d.x + "," + d.y + ")scale(" +d.scale+ ")";
  }

will help you It sounds like you're having a similar kind of issue that I had:
you want to fire event behind an element? The answer is CSS. Set pointer-events:none; to the parent.

I think the issue was by ths following , Should work. The events are triggered almost immediately. So you might not have seen the difference.
Encase the tiggering of mouseleave inside a setTimeout to see the difference.
code :
$( "#hover_to_show_text" ).mouseenter(function() {
   $('#hidden_text').show();
});
 $( "#hover_to_show_text" ).mouseleave(function() {
   $('#hidden_text').hide();
});

$("#hover_to_show_text").trigger('mouseover');

setTimeout(function() {
    $("#hover_to_show_text").trigger('mouseleave');
}, 1500);
// Just triggering the click event will not work if no
// click handler is provided.
// So create one first
$("#btn").on('click', function () {

    // trigger the mouse enter event 
    $("#hover_to_show_text").trigger('mouseenter');

    setTimeout(function () {
        $("#hover_to_show_text").trigger('mouseleave');
    }, 1500);

});

With these it helps I have multiple groups of svg elements in one viewport. I want users to click on one group which will hide the other groups and enlarge the selected group to fill the viewport. , There are two issues with the code:
code :
`$(".continents").css("display","none");`
currentContinent.setAttribute("transform","scale(1.0)")

this will help There are a lot of different ways to accomplish this, but to illustrate the point, the mouseleave event is triggered before the mouseenter which causes the div to slide down and up. You can do a simple check on the relatedTarget.
code :
if (e.relatedTarget && e.relatedTarget.id != 'd2' && e.relatedTarget.id != 'd1')
    $('#d3').slideUp();
if (e.relatedTarget && !e.relatedTarget.classList.contains('box'))
    $('#d3').slideUp();
jQuery detect element under element being dragged on mouseenter/mouseleave

To fix the issue you can do Figured out the issue, figured i may as well post the answer on the off chance someone's had a similar issue. The original issue was that i was setting mouseenter/leave event listeners on a div and trying to detect that div while dragging another element.
The resolution was to add the below css to the element being dragged, a setting I'd never heard of till now.
code :
pointer-events: none;
