To insert an element after a sibling element in d3.js, you can use the .insert() method along with the .node() method. Here's an example:


Let's consider the following HTML structure:

1
2
3
4
5
6
<body>
  <div id="parent">
    <div class="sibling"></div>
    <div class="sibling"></div>
  </div>
</body>


To insert an element after the first sibling element, you can use the following JavaScript code:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
// Select the parent element
var parent = d3.select("#parent");

// Select the sibling element
var sibling = parent.select(".sibling");

// Insert the new element after the sibling element
parent.insert("div")
  .attr("class", "new-sibling")
  .html("New Sibling")
  .insertAfter(sibling.node());


This code selects the parent element with the ID "parent", then selects the first sibling element using the class name .sibling. It then inserts a new <div> element after the sibling element, sets its class to "new-sibling", and adds the text content "New Sibling".


Note: The .insertAfter() method is not a native D3.js method. Instead, it uses the .node() method to get the DOM node of the sibling element and inserts the newly created element using native JavaScript.
