Comment (by aram.dermenjian):
It does work properly when circular. I just hadn't included "circular" as
one of the plots. The options were: cycle, cyclic, and circle... I'll go
ahead and add circular as well. Here is an example of it working if you
wanna check it out:
{{{
sage: p=SetPartition([['a','c'],['b',1],[20]])
sage: p.set_latex_options({'plot':'circle'})
sage: latex(p)
\begin{tikzpicture}[scale=1]
\node[draw,circle, inner sep=0pt, minimum width=4pt,
fill=black,label=90:a] (0) at (90:1cm) {};
\node[draw,circle, inner sep=0pt, minimum width=4pt,
fill=black,label=18:1] (1) at (18:1cm) {};
\node[draw,circle, inner sep=0pt, minimum width=4pt,
fill=black,label=-54:c] (2) at (-54:1cm) {};
\node[draw,circle, inner sep=0pt, minimum width=4pt,
fill=black,label=-126:b] (3) at (-126:1cm) {};
\node[draw,circle, inner sep=0pt, minimum width=4pt,
fill=black,label=-198:20] (4) at (-198:1cm) {};
\draw[-] (0:1cm) arc (0:72:1cm);
\draw[-] (72:1cm) arc (72:144:1cm);
\draw[-] (144:1cm) arc (144:216:1cm);
\draw[-] (216:1cm) arc (216:288:1cm);
\draw[-] (288:1cm) arc (288:360:1cm);
\draw[-,thick,color=black] (1.center) -- (3.center) -- cycle;
\draw[-,thick,color=black] (4.center) -- cycle;
\draw[-,thick,color=black] (0.center) -- (2.center) -- cycle;
\end{tikzpicture}
