While you are correct that in applications that have accessibility designed
correctly, there is an Accessibility Label for any graphical items of
significance to the user.

Beyond the UIA/MSAA/HTML labels used to describe graphics, JAWS can
In Excel charts glean the information in the chart by querying the Chart
object, in applications with static graphics, JAWS creates or finds a
graphic Id that is a number. It is not clear if this Graphic ID is based on
a hashing of the underlying digital information in the graphic, or if it is
somehow associated with information within the Windows OS. In any case, one
can associate individual graphic IDs with a text label in the "jcf" file
for a specific application. There is a JAWS shortcut insert-G that will
label the graphic under the mouse when you have the JAWS cursor enabled.
