There are lots of potential issues, all of which can be avoided by the
provision of redundant text links. These include:

Inability to see which area has focus. Often you cannot see the outline of
the area that has focus because there is insufficient colour contrast with
the background. Other times the area is very small. Sometimes the tab
sequence is all over the place so you don't know where to look.

Inability to identify the target of a link. This is a common problem when
using maps of countries - if I was looking for Dakota (for instance) I would
have no idea where it is on the map or what shape it is. Sometimes the areas
are so small that there is no room for a text label.

Common browsers do not support images maps well if images are turned off.
You would hope that the outline and alternate text for each area would be
shown, but this does not happen. You just see the outline of the entire map
and its alternate text.
