The chart on the right, from the Economist, displays revenues and profits of the 10 largest companies in the world in 2004 (as ranked by revenues). The graphic is yet another container of data: it elevates revenues, treating profits as a side thought. This table is clearer:
The next two charts attempt to put revenues and profits on an equal footing. I include the left chart to illustrate the folly of typical bar charts: the height of the bars serves no purpose except to distort our judgement of the lengths. The right chart is preferred.
But there is another graphic, favored by statisticians, that truly brings out insights from the data. Go to Junk Charts for more.
