How can I draw a circle slowly with noise?

Hello, I want to draw an audio histogram in a circular form.
I have completed an audio histogram that moves to linear, one side by referring to various tutorials.
But I have no idea how to make it a circular form or bend to perfec circle.
What I ultimately want to do : to draw an audio histogram in a circular form when a trigger is generated.

Wish every people who see this have a good day!

Hi @Metrics,

how is your histogram drawn at the moment - this is in TOPs?
Could you use a Projection TOP, setting the Input parameter to Equirectangular and the Output to Fisheye as well as the first Rotate parameter to 90?
You probably would want to change the resolution of the Projection TOP to something square and then recomposite…

cheers
