They produced a simple bar chart with a simple explanation of their findings: "Even with increasing restrictions on marketing, tobacco companies continue to compete fiercely for cigarette market share.

I like their color choices...good color variation and no one color sticks out much more than another. I typically don't like anything flashy, but the mouse-overs are quite good.
