On Nov. 14, 2010, The New York Times published this map of the world. This map gives several layers of information. The most noticeable one is the color-scaling that lets the reader use the legend to see how much tobacco ads are restricted in that country. The next layer of information is how much tobacco use has changed in 10 years. The last layer of information separates internet advertising from other types and lets readers see that the countries outline in black ban internet advertising.
The story this map accompanies is about how a global initiative is trying to further restrict tobacco advertising. I think making the map show what countries are a part of the initiative would either enhance it or make it interactive.
