title: How to visualize Fibonacci recursion?
body: <p>I am always struggling to visualize recursion because it isn't as straightforward as iterative approaches like while-loops and for-loops.</p>
  
  <p>It is easy to lose track of what is going on in recursion because we most often work with abstract concepts like values (numbers) and variables (x &amp; y). </p>
  
  <p>How can a recursive approach to the Fibonacci series be visualized in a way that avoids abstraction and uses easy-to-imagine metaphors?</p>
