Microsoft Excel software provides a very good platform to begin visual data explorations. Above Excel User link has some great examples of sites that provide support for this software. I am also recommending TinkerPlots software (not only for kids) which is pretty simple tool for creating plots and understanding how they work. Another software I have tested recently is ParSets, it creates multi-dimensional view of your data set and its free (check out the link above with some interesting examples).
