AREA
Description
The AREA element
specifies a single area of an image which, if selected, will
link to the hyperlink identified by HREF.
If multiple AREA elements in the
same MAP define overlapping areas, the first encountered takes precedence.

Variations
The AREA element is part of a proposed enhancement to
provide client-side image maps.
COORDS describes the position of
an area (in pixels) of the image in comma-separated x,y coordinates
where the upper-left corner is "0,0".
For SHAPE=rect (the default), it is "left,top,right,bottom".
For SHAPE=circle, it is "center_x,center_y,radius".
For SHAPE=polygon, it is successive x,y vertices of the polygon.
If the first and last coordinates are not the same, then a segment
is inferred to close the polygon. The NOHREF indicates that this
region should generate no links.
The ALT attribute specifies optional parsed character data to describe the area which
could be displayed by a text-only browser as a substitute for the image.
AREA is an extension in Netscape 2.0,
but the only SHAPE recognized is "rect", and ALT is not defined.
