You didn't cover Graph in this table -- is this because the implementation simply reuses HigherKinded.Class.removeVertex?
I think it would be nice to have an entry for Graph as well, since at some point we might change the implementation and it will no longer rely on HigherKinded.Class.

| **`removeVertex`**: Removes a vertex from a given graph. In `NonEmpty` graphs, returns `Nothing` if the resulting graph is empty. | ||

The first header here should probably be Data type instead of removeVertex (same for other tables).

| **`replaceVertex`**: Replaces a vertex `x` with a vertex `y` in a given `AdjacencyMap`. If `y` already exists, `x` and `y` will be merged. |

@mateoatr Many thanks for the PR! I've added a couple of comments above. Also two general comments:
I haven't yet checked the complexity bounds themselves -- will do that soon. |
