title: D3v5 and Django Rest Framework
body: <p>I'm having some trouble getting the following AJAX call to work.  I'm using D3 version 5 to make the following POST request to a Django REST Framework (DRF) ModelViewSet (version 3.x) view.  DRF provides the list of tasks under the path <code>/gander/tasks/</code> and allows one to create a new one by POST'ing to the same path.  I believe I'm retrieving the CSRF token correctly but I'm not sure I'm formulating the POST properly.</p>
  
  <pre><code>d3.json("/gander/tasks/?format=json",
   {method:"POST",
    headers:{
     "Content-type": "application/json; charset=UTF-8",
     "X-CSRFToken" : Cookies.get('csrftoken') },
    body:JSON.stringify({
     "parent": null,
     "name"  : "",
     "time"  : null}),
   })
   .then(json =&gt; {console.log(json);})
   .catch(error =&gt; {console.log(error);});
  </code></pre>
  
  <p>I've gone through the Django A.J.A.X. docs, D3 examples and a stack of S.O. Questions but they all refer to the D3-Request interface and I can't find any examples using the newer D3-Fetch API as above.</p>
