What Unity feature helps in organizing levels or states in a visual manner?

The correct choice is the Animator Window, which is instrumental in organizing levels or states visually in Unity. This feature allows developers to create and manage animations and transitions between different states of game objects or characters. By using the Animator Window, you can visually represent various animation states and how they transition from one to another, enabling a clear and organized way to manage the flow of animations in your game.

The Animator Window also provides layers and parameters, allowing for a more complex behavior setup such as blending animations based on player input or game conditions. Overall, it serves as a crucial tool for visually structuring and understanding the animated states throughout a level or gameplay sequence.
