Add comments

Add comments about the fractal at each code file.

The issue asks to add comments about the fractal in each code file. Start by exploring the repository structure to identify all Java files. Understand the Chaos game algorithm and how it generates fractals like the Sierpinski triangle. For each file, add explanatory comments describing the fractal-related logic, focusing on the mathematical or algorithmic steps. Run the program to ensure it still works after adding comments.
