Thats a brilliant requirement. If i was give such a requirement I would have built an extension like this:
A Force diagram which has circles, each circles size would be the measure(in your case revenue). So the ones with highest revenues would be the circles which are big. Now the top 5 big circles will be having the Images of the respective individual or divisions with a ranking badge attached to it.
Doing so as soon as you look at the visualisation you will be able to figure out the leader in a glance and obviously standout from others.
As this being a force layout, I can't tell you how much you they would love to play with it.
Let me know if you need help in building it.
Note: Make use of D3 to build it as this makes your life easier.
