Protovis pretty much covers everything, from what I can see. What you're looking for (I think) is an implementation on some specific data you have, mapped to hyperlinks from Wikipedia or similar? Please correct me if I didn't understand correctly or elaborate a bit.

Protovis is very close, but imagine one of the digital frames you put pictures in. The date dynamically creates the one image. Each element of the picture might represent a data element I feel is important. The javascript API will allow me to select the picture which could be a landscape or water-scape or mountain scape. The data can be encoded in JSON. The user could look at the image and have a visual representation of the data in a familiar format.
