nvd3 and its python/django wrappers appear to be no longer actively
maintained, and at least the wrappers were a bit clunky to use. Looking
around for a suitable replacement, Chart.js seems capable, has no
additional dependencies and is fairly simple to use. As a bonus we get
to drop a few Python dependencies from our list.

Use a more modern version of Bootstrap and take the opportunity to
upgrade jQuery to the latest version at the same time. This provides
better browser compatibility, moves to MIT license, allows us to make
the site more responsive for different devices in future, and provides
theming capabilities for custom installs among other improvements.
(I chose to upgrade to v3 for now rather than straight to v4 as it was
easier to do this gradually.)
