I know there are some tools and techniques for delaying the load of javascript, but I have an iframe that I would like to delay loading until after the rest of the page has fini

I don't understand why everyone is confusing JAVASCRIPT with JQUERY, but...
The pure JS solution is below: (basically it waits for the DOM to be built then loads all iframes in your page).

<script type="text/javascript">
      function load_iframes() {
var vidDefer = document.getElementsByTagName('iframe');
for (var i=0; i<vidDefer.length; i++) {
if(vidDefer[i].getAttribute('data-src')) {
vidDefer[i].setAttribute('src',vidDefer[i].getAttribute('data-src'));
} } }
      document.addEventListener("DOMContentLoaded", function(event) {
         load_iframes();
      });
    </script>
</code></pre>

<p><strong>Note:</strong> Be careful about using the document.load event. Any resource that has a problem or has to spend 1 minute to load will stop your code from executing. This code snippet is tweaked (replaced load by domcontentloaded) from this reference.</p>

             <div class="appendcontent">
