png and jpeg are bitmap formats, and you can trigger the resolution
playing with options width, height (in pixels) and res (nominal DPI)
till you find what is suitable for your purpose. Png is definitely the
way to go for graphs.
Pdf is the overall best option IMHO, but as already pointed out, word
cannot deal with it.
