Error while writing fibonacci.png

[kuldeepbishnoi]

I copied the fibonacci code and saved it as code.py file and tried to run but it failed to make png file and gif file but it created a folder "frames" and "fibonacci.gif" file. Would you please help me fix the issue?

# Import Visualiser class from module visualiser
from visualiser.visualiser import Visualiser as vs

# Add decorator
# Decorator accepts optional arguments: ignore_args , show_argument_name, show_return_value and node_properties_kwargs
@vs(node_properties_kwargs={"shape":"record", "color":"#f57542", "style":"filled", "fillcolor":"grey"})
def fib(n):
    if n <= 1:
        return n
    return fib(n=n - 1) + fib(n=n - 2)

def main():
    # Call function
    print(fib(n=6))
    # Save recursion tree to a file
    vs.make_animation("fibonacci.gif", delay=2)

if __name__ == "__main__":
    main()

Error:

Tried following version of graphviz with above installation:

and also added graphviz bin dir path to system path variable and successfully verified it using dot -V
