Collatz Conjecture Visualization

The Collatz Conjecture states a simple maths algorithm:
1. Take any number and call it _a_
2. If _a_ is even, then set _a_ equal to _a / 2_. Otherwise, if _a_ is odd, then set _a_ equal to _3a + 1_
3. Repeat step 2

This trivial problem is famous because it has never been proven if every plotted integer converges to 1. You could do a problem that desings a tree starting with 1 and building its way up.

It seemed easy until I started programming it.

No repository files, tests, or entry point are identified. Start by reviewing the linked Collatz visualization references and determine where a tree starting with 1 would fit in this suggestion-only repository. Done means the visualization scope and implementation location are established, with the reverse Collatz tree represented as described.
