How would I implement a model of a recursive Fibonacci sequence on Simulink?

hi

I'm trying to understand Simulink and I wanted to know if anyone has implemented a Fibonacci sequence with a graphical diagram.

Apologies if this is not very clear. I mainly just want a visual representation of it because I am dyslexic.

Thanks

    function fib = recursiveFibonaccifinal(N)

    if N==0 % Termination condition no 1
            fib = 0; 

    elseif 
    N==1 % Termination condition no 2
            fib = 1; 

    else
            fib = recursiveFibonacci(N-2)+recursiveFibonacci(N-1); 

    end

    end
