Thanks so much, Sébastien. I `sage -i dot2tex`-ed on 9.6.beta5 and that fixed the problem. Is this something that should be included in the documentation? If so, I can open a ticket and add it, but where do you suggest I do so? The documentation for `view()` <https://doc.sagemath.org/html/en/reference/misc/sage/misc/latex.html#sage.misc.latex.view> seems like too generic of a spot, and as far as I can tell, there is no `Poset.view` method in the documentation. One option would be to add a view method, but that may conflict with the show method and cause confusion.
