I think not ... I think that list can be used for simple cases ...
powerfull data-grid style would be more like a component, imo more than

maybe you should wait if you are not sure about the idea ....

hmm, different needs, different purposes ... as for the display, graph
can be OK, but if you need to print e.g? As for trying to build some
examples ... is it reall advatage of RFM/ADM or just of its
implementation? We should compare how data are organized, what it allows
us to do in upper layers, etc., as I can find some nice tool working
with relational model under the hood ... unless I don't miss something
