I have always wondered with what programs do people do their graphics when they publish papers. They most of the time seem to be embedded in some way as vector graphics, I'd say, as when I try to zoom the pdf it seems it computes the image in the moment, it doesn't seem to be a image. From their aspect they don't seem to be just print screens of Mathematica plots.
Here are some examples of what I mean:
Anyone knows what should I use to be able to do similar graphics?
(I've put a latex tag as I believe it has something to do with it)
