So exactly what kind of comparison visualization tool are you looking for? If you are just interested in a better visualization than diff(1), there are various GUI frontends such as kdiff3, meld, kompare and so on that makes diff's easier to read with color-based highlighting, but not sure if you are referring to this kind of diff frontends. ---
