Make a cursor on a half circle

I want to create a semi circle on which I’d like to add a cursor that will move from the left to the right according a score :

0/10 it will be at the beginning and 10/10 it will be at the end.

I have tried to create something using radial-gradient and conic-gradient, but I’m not sure it the right way to start that.

Here is a jsfiddle showing that.

Thank you for your help
