Why would graphite-webapp browser not display any body content?

I have used 0.9.x Graphite in the past as the basis of my monitoring system, and am trying a fresh install of 1.0.1 prior to upgrading across my systems (Ubuntu, 14.04, though I doubt that matters).

I appear to have graphite-webapp and carbon-cache running (supervisorctl reports both as RUNNING, and there are not errors in any logs I can find). I have confirmed by navigating in the server /opt/graphite/webapp/storage/whisper/ that there is in fact data to display in the first place.

I am able to access http://localhost:8080 and see the usual graphite webapp header, but the body of the page is blank (where normally I would expect to see the file-browser that lets me choose data on the left, and it graphs the selected data on the right).

To the best of my knowledge, I have configured graphite as per the installation instructions, but obviously I have done something wrong.

If there are particular configuration files that would be useful for me to include (which can also server as a debugging path for future people who may have this issue), please comment the files that may help.

Note to editor: The tag should be "graphite", probably, but I don't have the rep to tag it correctly.

You need to collect static assets in your Django

cd /opt/graphite/webapp && PYTHONPATH=/opt/graphite/webapp django-admin.py collectstatic --noinput --settings=graphite.settings

Static files will be installed in /opt/graphite/static.
Then you need to configure your webserver to serve them directly.
For Nginx something like:

location /static {
   root /opt/graphite
}
