Django has the function render (it used to be render_to_response) that takes a template and converts it to HTML. So it isn't just the JS people who are using the idea of rendering in this sense. More generally, rendering doesn't necessarily mean something visual; for instance, one may talk about how a phrase in one language is rendered in another language.
