New image map component

Hello group, I am planning to make a new image map component for pier. Does anyone know of anything like this pre-existing? If not I need a little bit of help: I want my Image map Pier component to be configured from the settings command so I need to know how to use Magritte to build the GUI. My ideal representation (at least that I have thought of so far) would be a Dictionary. For every Coordinate string there is an image string (file location) to go with it. It is a direct one to one, but the two members of this relationship are both strings. And I want them to wind up getting added to the dictionary. My preference would be that the ImageMap component has a #addCoord:withImage: method that gets called for each entry. I did not see how this could be done in Magritte from the tutorials or source code. Anyone got any ideas? Thanks in advance.
