This method generates a PDF of the Hasse Diagram of the Poset view LaTeX code which uses TikZ. The method attempts to display the PDF using show. See texPoset for more about the representation.
Normally, the vertices of the Poset are placed at regular intervals along horizontal lines. However, this can sometimes cause edges to appear in the Hasse diagram that are not truly there. The Jitter option can be used to randomly shift the positions of the vertices horizontally, which can often cause the edges to be more clear.
The object displayPoset is a method function with options.
