Beginner circuit design - how do I finish this thing off!

The diagram attatched is for a 3 bit counter ive designed but I want to be able to see it working by simulating it in a program called 'Electronics Workbench' - how do I finish it off i.e wire it up (yes, its probably a laughable question) with an appropriate visual output so I can see it working on screen, bearing in mind I can't see any obvious visual components to add?

well connect the A,A`,B,B`.... to the respective D flip-flop, A is the Q output of the A FF, A` is the Q` output... then put an indicator of some sort, LED.. on the outputs of the D-FFs
