you would build an image map JSF component.

I already created such a component,, but maybe its too limited to get 
added to myfaces.
Its sort of "my first component" and maybe too restricted to my 
application.
I used it in conjunction with jfreechart to be able to click into the 
graph.

It works like this:

<h:inputHidden id="annotateEvent" value="#{AnnotationForm.eventNumber}"/>
<h:graphicImage
       binding="#{EventDataProvider.image}"
       url="#{EventDataProvider.url}"
       alt="WateringData"
       width="900"
       height="600"
       usemap="#CHART_TOOLTIP"
       />
<s:area
       mapName = "CHART_TOOLTIP"
       action = "annotateSpot"
       areas="#{EventDataProvider.areas}"
       destField="annotateEvent"
       />

The hidden field is required for the s:area component (see destField=). 
With my knowledge today I could get rid of this hidden field.
The areas are passed in through an ArrayList of ImageMapArea.java 
instances which is a simple bean with "shape, coords, title and data". 
data is the value you might find in "destField" then.

Sayed all that: If one find it useable that way I can contribute it.
