The colored shapes on the left go to different web sites except the bottom
right one which only displays a tooltip. The two text areas perform the
actions they describe.
The colored areas in the image map on the right post back to the server.
The areas in the right side image map will also fire validation events as
demonstrated by the required text box below.
The right-hand image map also demonstrates adding other HTML attributes to
the image map such as onmouseover and onmouseout events to show and
hide a message for the image map control as a whole and to change the image when the
mouse enters the clickable image map areas.
