The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Monthly Hask Anything (October 2021)
Even a fairly simple statement like "F preserves direct limits over N" is basically impossible to express like this. You can step further from Hask and work at the type level until the very end (which I believe is the approach taken by data-category), you can resign yourself to only expressing things that can be "defunctionalized" (an appropriate use of the term, I think, if not a correct one) down to Haskell functions, which gets you (Co)Yoneda, Lan, Ran, etc. in the general case and I think Traversable in this particular instance, or you can take some intermediate approach with constrained functions and/or explicit witnesses in your data types, but you can't make proper category theory "just work" the way it should.
What are some alternatives?
When comparing type-iso and data-category you can also consider the following projects:
buffer-builder - Haskell library for efficiently building up buffers
data-lens - Haskell 98 Lenses
filesystem-trees - Traverse and manipulate directories as lazy rose trees
data-lens-fd - Lenses with Functional Dependencies
proto-lens - API for protocol buffers using modern Haskell language and library patterns.
cassava-conduit - Conduit interface for cassava [Haskell]
fclabels - First class composable record labels for Haskell.
total-map - Finitely represented /total/ maps
monoid-extras - Miscellaneous constructions on monoids
kan-extensions - Kan extensions, Kan lifts, the Yoneda lemma, and (co)monads generated by a functor
