Create a model for the dynamic system that illustrates the deterministic chaos phenomenon and the self-organized criticality characteristics of a file system. Define variables for storage size, file sizes, file load time, file access time, file save time, fragmentation time, fragments assembly time, critical threshold that triggers a system too slow alert, and other variables as need.

Implement the model as a computer program. The program should display a visualization of the fragmentation process as a sequence of save and delete commands are received. While you have a certain measure of freedom to choose your techniques for visualization, consult the instructor to ensure that your approach is acceptable.

Your program should also display a graph showing the appropriate metrics approaching the critical point (e.g. a line chart).
