Fig. S6.

Cluster analysis at different volume fractions: (A) $\varphi =0.07$, (B) $\varphi =0.09$, (C) $\varphi =0.15$, and (D) $\varphi =0.20$. Systems all have $N_d:N=$ 1:47. (A–D, Top) Snapshots of cluster formation at $t=2\cdot {10}^3$ ${\tau }_b$. Only the clusters with $S_C>=4$ are highlighted for clarity. (A–D, Middle) $⟨\mathrm{\Delta }{r}^2(\tau )⟩$ curves per particle (gray) and the ensemble average (red). (A–D, Bottom) Histograms of the $⟨\mathrm{\Delta }{r}^2⟩$ at $\tau =5\cdot {10}^2$ over 50 bins.
