Actually concerning visualization tasks I don't see a sense in one line solution because as I think you should understand how you want to represent your data and this has strong influence to calling signatures.
For almost all issues, you can simply search for site:stackoverflow.com + the title of the issue and get a larger variety of solutions ranked by upvotes, so this repository seems strictly worse. Is there any advantage that this repository brings over just searching for the question on StackOverflow?
I didn’t review all of the code, but the examples I saw seemed to have some basic explanations with them. Additionally, they have samples for a lot of different technologies. A curated repo seems much nicer than scoring several StackOverflow answers. Depends on the code quality, of course.

The README explains that they want a single curated answer, not a list of 15 answers with 25 comments. This does seem worthwhile, at least for some types of questions.
Sure, sometimes the top voted answer is not the answer to my particular problem at hand, but if it isn't, I'd rather have more alternative answers than nothing.

The code quality seems questionable. A few examples: Repository claims modern code, but uses Python 2 (end of life January 1, 2020) https://github.com/Onelinerhub/onelinerhub/blob/main/python/...

I looked at the C# ones - the code is not great and neither are the explanations, both show a lack of experience in C# and .NET. How to reverse the characters in a string String.Join("",("1234Simple").Select(c=>c).Reverse()); - String.Join("", - concatenate one or more characters in a single list or array, by using empty "" string literal separator - .Select(c=>c) - select each and every other character in a string i…
How often do you want to reverse a string.
I think your solution is fine and isn't "bad code" at all. Certainly a real explanation warrants talking about the IEnumerable interface.
I'd also consider the simpler (and ever so slightly better performing):
var buffer = "1234simple".ToArray();
Array.Reverse(buffer);
new string(buffer);
var buffer = "1234simple".ToCharArray();
Array.Reverse(buffer);
new string(buffer);
But to re-iterate and to add to your criticism, I can't understand the use-case of needing to do this outside of toy problems.
"Generate random array" (python-numpy)"
Ok - but what dimension? size/length? what range? sample from what distribution? only unique values? etc.
Many of these problems have "native" one-liner numpy solutions which are trivial to find (basically just read the documentation).
I learned J before NumPy and I'm glad I did, because it's much easier to see and learn the algorithms when they're short symbols. Compare np.sqrt(sum(np.square(x))) versus %: +/ *: x So if you can translate one of the array languages to NumPy, you can tap into the wealth of "idioms" collected over the years. For example: J Phrases[0] (organized by category), BQNcrate[1] and APLcart[2] (searchable). [0]: https://www.j…

Isn't the "curated" answer on Stack Overflow the answer with most votes? Sure, sometimes the top voted answer is not the answer to my particular problem at hand, but if it isn't, I'd rather have more alternative answers than nothing.

Indeed, their example is terrible, because it's also the kind of 'toy' problem that just doesn't have good real world uses too. How often do you want to reverse a string.

Not sure, not my domain, but perhaps bioinformatics has the equivalent of the convolution operation on sequences?
EDIT: there is the "reversal" operation. Peeking ahead from the Rosalind problems, I'm not quite up to Reversal Distance (https://rosalind.info/problems/rear/).
