All well and good, but do they use high school kids to design their graphs over at Time?
Hmm, what color should we use to represent oranges on this graph?
Well, we've already assigned orange to Apples, so we might as well make Oranges purple.
Ok, now let's make potatos green, and lettuce grey, that won't be confusing at all.
Now, let's make celery and tomatoes the same color, but put them at opposite ends of the legend and maybe nobody will notice.
As for Lemons, let's make them blue, because nothing suggests lemons like the color blue. Of course, that leaves brown open for bananas, which is logical. Might as well make strawberries green too.
Seriously, it is not hard to make an easy to read, intuitive graph.
