Extended Data Fig. 2: Optimizing Model Selection for Policy Impact.

The x-axis represents the number of connected components (groups) in each graph, while the y-axis shows the variance of Total Nameplate Capacity (MW) within groups. The optimal model is chosen at the inflection point (elbow) where increasing the number of groups no longer significantly reduces the variance, balancing model complexity with meaningful group differentiation.
