Yeah seeing more datasets would definitely be nice. I linked my GitHub repo where I made the changes necessary for this example in the YouTube video. Using the last commit (the only changes from upstream) as a guide, other datasets cold be supported similarly.

That said, I don't think my choice of data is that bad actually. Apparently starting with a sorted dataset, appending some new items, and then sorting the result again is very commonly done by programmers. That is essentially what's represented in my example.
