The line graph illustrates empirical SCFI entropy-based resilience dynamics over the period from January 2021 to January 2025. The x-axis represents the date, ranging from 2021 to 2025. The y-axis on the left represents the SCFI values, ranging from 0 to 5000. The y-axis on the right represents the normalized entropy or resilience, ranging from 0 to 1. The graph includes three data lines: Observed SCFI, Normalized Shannon entropy, and Entropy-based resilience score. The Observed SCFI line fluctuates significantly over the period, showing peaks and troughs. The Normalized Shannon entropy line also shows variability but generally follows a different pattern compared to the Observed SCFI. The Entropy-based resilience score line exhibits its own unique fluctuations. All values are approximated.Empirical SCFI entropy-based resilience dynamics, 2021–2024
