Any tree diagram can be made radial, and it will look fabulous lol
Usually, a tree feels like it is going in one direction. It starts at one point, then keeps branching downward or sideways. Because of that layout, your brain reads the structure as a path moving forward.
But the same tree can be placed around a center. The root sits in the middle, and every level moves outward as a ring.
Because now labels of tree can be visualized as bands in circle (rings of onion.) It becomes about distance from the center and its peers.

Maybe you can use this new circular form to run comparison with other things in radial or polar arrangements
But it’s all about the transformation you do to get it into the radial form right?
There must be only few ways to do it so that you can keep the comparison with other radial things alive
Because just in the image provided I have shown two different methods to do it. And I bet there are tons of more.
