Which makes you require software again, so what's the point exactly? A cool idea for a logo stored as SVG cannot be visualised by a human, neither can text data rows of a CT scan or a stress visualisation from an FEM or FEA simulation. What you call "merely a visualisation" in many cases is the data you (as a human being) are actually interested in; the storage format is an implementation detail and I'm very surprised how this clear distinction seems to be ignored by some.
