调研方向
The issue proposes wide and long data reshape functions for d3-array, inspired by pandas and tidyverse, but names no files or tests. Start by reading the project’s existing array APIs and conventions, then assess the scope and expected behavior for reshape operations. Done would mean agreeing on an API and implementing and testing the requested transformations; the issue has had no comment for over five years.

描述
What are your thoughts on adding data reshape functions similar to the melt and wide_to_long functions in pandas or pivoting, gather and spread in the tidyverse?
It's a very common pattern when loading data for charts, such as in the multiline example. I find myself frequently writing these reshape functions in each project and they're often some of the least literate parts of my code. They're especially distracting when trying to teach people chart concepts and they hit a big speed bump right off the bat.
Anyway, it would be a great addition to the JavaScript world. If there are other packages that have already done this that I missed, let me know. I've seen a few "let's rewrite pandas/dplyr in js" packages over the years but none ever gets completed, let alone maintained. Happy to be wrong, though, if someone has broken off these functions somewhere!
