Is there a way to convert shader code to diagram?

Forgive the (perhaps) stupid question.

Websites like https://godotshaders.com have many interesting shaders but it’s all code and Godot 4.3 comes with a diagram editor.

Is there a converter or some such for those of us who understand so little that copy/paste is our best hope to begin playing around with shaders and begin learning?

Shaders are freaky.

Thank you all.

It was a stupid question. Kind of.

In case anyone has a similar problem, just choose Shader instead of Visual Shader in the Material group.

Still, it would be nice to be able to convert code to diagrams.
