No, you misunderstand. The quoted text refers to the main image itself,
and that your text alternative for it at least knows in very broad
general terms what it is (in your case, "Map of the UK"). The actual
functionality of the map itself must still be made accessible (either
directly, or provide an alternative such as a table or just a flat
separate page that lists all areas of the UK and provides that
information you'd get when clicking on each bit).
In short, the text you quote does not absolve you from making this map
