We numerically calculate the full static structure factor to reveal a topological phase transition between a fractional Chern insulator (FCI) and a generalized Wigner crystal (GWC). We further calculate the quantum weight of various FCI states, verifying the universal topological bound for interacting systems. Our findings provide insights into the phase diagram of twisted TMDs and establish a general framework for characterizing topological phases through structure factor analysis.
