It's barely related to django. If all you want is to make annotation, it's fairly easy and you don't really need canvas and it's mainly javascript, which is independent from django. First, display your image. Second, get where your user want their annotation. I would do that by listening to click event on the image and computing the position of the click in the image, which is position of the click in the page minus position of the image in the page. Third, get the actual annotation. Fourth, send to django a request to store an annotation on image Z at position X / Y with text T.
Fifth is to display the image. Get all the annotation for the image, display dot at the position of each annotation, display the text on mousehover. Or directly on the image if the image is huge.
