I understand it's asking a lot to draw complexes in dimensions $>3$, but for (fairly simple) 2 dimensional complexes, it seems reasonable that some plotting algorithm should exist. Even looking at, say, simplicial_complexes.Torus(), it doesn't seem like there's a plot or show method. The docs1 don't seem to have any information either.
Since the things I'm trying to draw are fairly simple, I would be wiling to plot the $1$-skeleton (which sage can do) and then fill in the $2$-cells myself, but I'm not even sure how to go about doing that. Obviously if there is a pre-existing method or library for this, that would be the best possible solution.
