What is a fish diagram?

The term "fish diagram" can refer to a few different things, so it's helpful to clarify what you're asking about. Could you please be more specific?

For example, are you referring to:

* A diagram of a fish's anatomy? This would be a diagram showing the internal and external parts of a fish, like its fins, gills, scales, etc.

* A fishbone diagram (also known as Ishikawa diagram)? This is a tool used in quality management to identify and visualize the potential causes of a problem. It looks like a fish skeleton with the problem at the head and the possible causes branching out like bones.

* A diagram used in fishing? This could be a map of fishing spots, a diagram of fishing knots, or a diagram showing how to use different fishing gear.

Once you clarify what kind of "fish diagram" you're interested in, I can give you a more specific answer!
