Circle Texture - Procedural - Blender 4.3

Blender doesn't have a circle texture!!
This is very surprising, so i made my own circle texture.

Instructions: in the shader editor, press shift+a > group > circle texture to get it.

FAQ:
Q: it doesn't show up, what happened?
A: Connect a texture coordinates node to the vector input on the circle texture node :)

Q: can i see how it works?
A: press "tab" while having the circle texture node selected to see the "inner workings" of the node.

Q: the texture is PINK!! what happened?
A: chances are you didn't download the leather texture included!
