Great work, but would be great for a frame of reference to add something at the end that zooms back out (and maybe uses a different scale to fit on screen) that shows you against everything. As soon as I discovered to click to go to the next tier, I just kept clicking and didn't pay attention to how many levels, how many people, etc. Otherwise great work!
