It should return a dict with three items:
- **label_on_separate_line**: the output is normally a two-column
table. When this option is set to True, the label is printed on a line
of its own with the value on a whole line of its own, below. Used for
big google graphs.
- **label**: the label. Shown in the first column.
- **value**: the value to show. Use ``mark_safe()`` when returning a bunch
of html. Note that we do some html rendering here ourselves instead of
in the template as we know which rendering methods to use here in this
file. The template *used* to be littered with exceptions, being tightly
coupled to the constants in this file. Not anymore.
The value is rendered based on the ``render_as`` attribute of the
featureline. See :ref:`popup-choices` for the available choices.
