Translating JSON into custom dijit objects

Question

I am looking for an example where JSON constructed from the server side is used to represent objects that are then translated into customized widgets in dojo. The JSON would have to be very specific in its structure, so it would not be a very general solution. Could someone point me to an example of this. It would essentially be the reverse of this
