I am having a hard time conveying to my co-workers why I think that what they consider "advanced", "high-quality" scientific graphics1 does not hold a candle to what one could do already do with Mathematica back in the late 80's, let alone now.
It would bolster my case if I could show them a single gallery of the sort of stuff that only Mathematica can do, thanks to the generality of its conception of graphics.
Over the years I've seen zillions of impressive Mathematica graphics demos, but I'm having a hard time finding a big, easily-browsable collection that shows off Mathematica's power as a platform for generating scientific graphics.
NB: I am particularly interested in 2D plots, mostly because the libraries whose feebleness I'm trying to demonstrate can do only that.
1For the sake of politeness, I won't name the software and the graphics libraries that my co-workers are so impressed by.
