I will discuss joint work with Terry Song studying dual boundary complexes of moduli spaces of maps from smooth pointed curves of genus g to projective space, for g = 0 and g = 1. In genus zero, a normal crossings compactification is provided by the Kontsevich moduli space. In genus one, a normal crossings compactification was given by Vakil and Zinger, and later furnished with a modular interpretation by Ranganathan, Santos-Parker, and Wise. I will discuss the geometry of these compactifications and the combinatorics of the resulting dual complexes. In particular, in both cases the dual complex will be seen to be contractible.
