Vector graphics is smaller than bitmap for same (medium to good)
quality, in theory and in practice, often an order of magnitude. Of
course you can do stupid things with vector graphics too, i.e. one may
squeeze to much data points into a diagram, much more than eye can
resolve (I did it myself years ago ...)

PDF is not always vector format, it may contain plain bitmaps!

Some time ago I told someone to use PNG instead of JPEG to display
schematics on web pages -- he converted the JPEG with all its dirt and
artefacts (lossy conpression junk) to PNG to show me that filesize and
quality is not better with PNG ;-)
