This is a topic of some interest to me. Some of the works that you mention (Fry etc.) bring up the question of the intention behind some of the visualization works that are created in the context of scientific or design practice, but which are often presented (hence understood) in an art context. How does this impact the understanding of the work? Manovich points out that these days data visualizations can provoke more emotional reactions in audiences than a lot of more conventional art objects.

One of my favorite artists in this respect is Jason Salavon (see this previous post). In his work Shoes, Domestic Production, 1960-1998 meaningful statistics about shoe production in the US are intentionally reduced to meaningless but beautiful mandalas of color. It is an ironic comment on visualization as art.
