bad graph of the day

In the plane to Trondheim, I spotted this ludicrous graphical representation of the sales of cars in France during the first trimester of 2012. While the ration “diesel”/”essence” is four to one, the areas and scales of both sets are completely disproportionate! And this is reinforced by the representation of the larger set as a one-fourth disk, hinting at a scale four times larger… (I do not know if Le Monde or the ” comité francais des constructeurs d’automobiles” (CCFA) is responsible but I would suspect Le Monde after checking on the CCFA site… It sounds like Le Monde needs a journalist with better statistical skills.)
