It's not that easy to do the untangling even manually though. – Szabolcs

Maybe you could turn it into a puzzle and let other people do the untangling :-) – Heike

I could make a web based game, and feed all my graphs to the visitors.
SE is a big game, isn't it? :D – Szabolcs

@eldo I think that author was just trying to be funny, not negative or offensive. We usually welcome a limited amount of light humor around here.

eldo, you deleted your Riffle question. Are you planning to resurrect that (clarified, hopefully)? Do you have your solution?

comment Find sublists of a list that match some conditions
@YuYong Or @@@ is to convert a list containing True to True: Or @@@ {{1, 2, 3}, {4, True, 6}} outputs {1 || 2 || 3, True}. Then TrueQ /@ converts anything not explicitly True` to False: TrueQ /@ {1 || 2 || 3, True} outputs {False, True}.

comment How to label a histogram operating on a dataset?
@alancalvitti What do you mean by "inline" in this case? Would you prefer titanic[(x \[Function] Labeled[Histogram@#, x] &)[#], #] & /@ {"age", "survived"} ?

comment Why do quote marks appear in output when saved with Save Selection As?
@Simon I confirm that behavior as well. Thanks for being thorough. I should have checked that myself.
