A quiver diagram is like a picture book that tells a story about how things are related to each other. Just like how you read a story from left to right, a quiver diagram has arrows that go from one thing to another. These arrows show how things are connected or how they move from one thing to another.
For example, let's say we are talking about animals. We could draw a quiver diagram with arrows that show how a mouse eats cheese, and how a cat can chase and catch the mouse. The arrow from the mouse to the cat shows that the cat eats the mouse.
Overall, quiver diagrams are like maps that help us understand how different things are related to each other, and how they interact with each other.
