Implementation of SVG shapes, don't know how to do?

Question

Animation

We need to implement something like this in SVG. Tell me how to do it.
I know how to make a stroke, I know how to make the ends of the lines round, I know, but how to make the pieces of the sections be in the form of lines in a circle, also with the ends round, and all this needs to be animated (I think I can handle animation), but here's how it is draw, I don’t know, I have little experience. Maybe someone will help.
