Russ said it better than me. You simply return the serialized JSON string as the HttpResponse. You then deserialize it somehow in the client's Javascript code (perhaps with an "eval" statement or by the assistance of a Javascript library like jQuery, etc.). You then have a nice Javascript object that you can manipulate and use to add points to the map in Javascript.
I have implemented something like this before with PHP and Javascript. I am converting it to my Django powered site. My current client code is straight Javascript. This time I intend to leverage jQuery to make my code smaller, and hopefully a bit more portable. If you want to see how I did it in plain old Javascript, my old code can be found here: https://sourceforge.net/projects/membermapnuke/ If you drill into the code look for mmap.js for the client side stuff and ajax.php for the server side. I'm porting this to Django at the moment, and I'm looking forward to trying out Django's serializer for this.
