For the curious, with the latest sage-combinat patches:
sage: B = CrystalOfTableaux(['B',3],shape=[3/2,1/2,1/2])
sage: view(B, pdflatex=True, tightpage=True)

The latex/dot2tex code in graphs already handle bounding boxes properly:
sage: G=B.digraph()
sage: G.set_latex_options(format="dot2tex")
sage: view(G, pdflatex=True, tightpage=True)
This sounds like a good enough incentive to finally get rid of our
Sage Days 7 quick hack, and have B.latex use the latex/dot2tex code
for graphs, doesn't it?
As for compactness, one could indeed use the signature, and possibly
combine it with the LaTeX function of Tableaux. Here is a quick hack
to see what it could look like (please check; maybe a revert is needed):
sage: def spin_latex(self): return latex(Tableau([[i] for i in
self.signature()]))
sage: sage.combinat.crystals.spins.Spin._latex_=spin_latex
sage: view(G, pdflatex=True, tightpage=True)
Cheers,
Nicolas
