and the second, a graph of the most populat combinations:
If you are interested, the full research questions are:
- How many packages directly depend on the mtl library? What is their
distribution with respect to package metadata, such as names, versions, stability
- What monads, or notions of computation, defined in the mtl library are
the most popular?
- How popular are alternative implementations to the mtl library?
