The fractal shapes are squished horizontally

The fractal shapes are squished horizontally and need to adjust the range.

Look for the code that defines the drawing area or coordinate ranges for the fractal shapes. The issue mentions adjusting the range to fix horizontal squishing. Run the program to see the current output, then modify the relevant parameters in the drawing logic. Check if there are any existing tests for visual output to verify the fix.
