How to plot an arc shaped figure?

I would like to know how to plot something similar to the picture here in below. As we can see, the plot is on an arc of a circle.

Try this

t = linspace(0,pi,500);
x = cos(t).*(1 + 0.1*cos(30*t) + 0.05*sin(100*t));
y = sin(t).*(1 + 0.1*cos(30*t) + 0.05*sin(100*t));
plot(x,y)
axis equal

Thank you for your attemp. But, my question is asking about how to plot the arc shaped plot where the whole box of the plot is on an arc.
