    Convert mpl plots to locally hosted HTML documents.

    This function should be used with the inline matplotlib backend
    that ships with IPython that can be enabled with `%pylab inline`
    or `%matplotlib inline`. This works by adding an HTML formatter
    for Figure objects; the existing SVG/PNG formatters will remain
    enabled.
