I tried this at home on my Mac. Tornado was already installed, so I
updated it to 3.2.1, and ran a Matplotlib app I have which allows me
to set the backend on the command line. I get the exact same behavior
as at work on my Linux desktop. I get a page at 127.0.0:8988 with a
"Figure 1" link. Clicking that takes me to 127.0.0.1:8988/1, which is
a blank page.

Chrome is my default web browser on both Linux and the Mac. I manually
visited the page from both Firefox and Safari, clicked the link,
and... nothing. The same behavior as on Chrome.

Then I had the bright idea to look at the JavaScript console. It shows
this error message:

  Uncaught SyntaxError: Unexpected token &

Clicking that error took me to this line:

var fig = new figure('1', websocket_url_prefix);

Are those entities supposed to be ''? What bit of code generates that
JavaScript?
