The `TemplateHTMLRenderer` will create the template context with keys `data`, `request`, `response`, `view` and determine a template name to use to render it.
The TemplateHTMLRenderer will create a `RequestContext`, using the `response.data` as the context dict, and determine a template name to use to render the context. **Note:** For compatibility reasons, the context may contain all response data at the top level as well as the `status_code` key.

**Note:** When used with a view that makes use of a serializer the `Response` sent for rendering may not be a dictionary and will need to be wrapped in a dict before returning to allow the TemplateHTMLRenderer to render it. For example:
```
response.data = {'results': response.data}
