    • (edited Nov 25th 2022)

    I have made explicit that comonoids first of all come with a counit

    and I have added diagrams (via a quick tikzcd hack, please feel invited to replace and improve) to make explicit that:

    • a string out of the little bubble denotes the unit,

    • one into the little bubble is the acual counit.

    Because, probably a reader who does not already know about unital comonoids would need to be told this.

    Finally, I have hyperlinked “string diagram”.

    Have slightly expanded the wording in the example (here) of comonoids in cartesian monoidal categories.

    (I seem to remember that we had a broader discussion of this point in another entry, but I forget where excatly.)
