No, but there are many add-on components available from <http://

Magritte doesn't know how to add and remove entries from a
dictionary. Of course, this can be changed, but I think the easiest
would be the following:
1. Create an Area class with described fields for the coordinate and
image string (exactly as in the tutorial).
2. Create a subclass of PRStructure with a field to hold the areas.
Describe the field with something like:
^ (MAToManyRelationDescription selector: #areas label: 'Areas'
priority: 400 default: OrderedCollection new)
classes: (OrderedCollection with: Area);
yourself
That should work (untested).
Cheers,
Lukas
