Deaths in millions by cause worldwide

Trachea, bronchus and lung cancer appears twice, as both 0.46 and 0.57. Combining the two would put it ahead of malaria, but I suspect that one of the entries is a typo, and should say something else. Stroke perhaps?

Actually, it's because the data wasn't combined before creating this graph. If you look at the full dataset at http://www.swivel.com/data_... you'll see that it lists the number of deaths based on the income bracket of the country. So Trachea, bronchus, lung is listed three times, with a number for low, middle, and high income countries. The author needs to combine all three for each figure and republish the graph, or, more accurately, create three separate graphs for differing income levels.

It could also be that some of the conditions have slight typos in the entries, where it looks like for one income level it is listed as "Trachea, bronchus, and lung" and for another "trachea, bronchus, lungs." I would guess the slight difference is fouling things up.

There are slight variations between some other conditions, as well. The names should probably be normalized.
