A legend title such as “legend,” “symbols,” “key,” or “map key” can be associated
with the legend. If a title is used, ensure that it does not obscure the main points,
which are the items and labels. For that matter, it may be better to eliminate the
legend title altogether as it is usually obvious what the items and their labels are.
A floating legend (explained later) within the map element may be one situation
when the title is more necessary in order to provide clear separation between the two
elements, especially if there are other floating text boxes on the map.
