#Dark Blue Square (High Positive Correlation): Intelligence and strategic value are highly correlated (~0.86). In Dr. Stone, top-tier intellect (like Senku) directly drives strategic importance.

# Faint Orange/White Squares (Low/No Correlation): Physical strength shows a weak negative correlation with intelligence (~ -0.15) and almost no relationship with overall strategic value (~0.05).
