Dartboard Chart - Excel Newbie

So at work we want to develop a dartboard style chart that will show an agent's accuracy for eight different queues, where the closer to the center a point lies the greater the accuracy. From what I've looked up so far the bull's eye format gets me the closest but I'm having difficulty grasping how to make it work in eight wedges basically. Is there a template that would get me closer to this or another way to seek assistance developing one?
