The point of archive is to acquaint abstracts effectively. Or, at least, that is the point according to data-visualization experts. The accuracy about why bodies like and use archive is added complicated than that. For the approved person, it’s added about art than science. There is no bigger affirmation of this than the acceptance of the pie chart.
The pie blueprint has continued been reviled by data-visualization experts. “The amphitheater with sectors is not a adorable anatomy of presentation,” wrote the architect and decision researcher William Brinton in his 1914 book Graphical Methods. Brinton believed pie archive were difficult to analyze and that it was about consistently bigger to use a bar blueprint to back information.
Over the afterward century, about every added austere blueprint maker came to the aforementioned conclusion. Experimental affirmation additionally backed them up. In a cardboard appear in 1984 (paywall), statisticians William Cleveland and Robert McGill showed that bodies are abundant added acceptable to accurately appraise advice back it’s put in a bar blueprint than in a pie chart. This is because bodies tend to belittle the admeasurement of astute angles (90°).
Today, pie archive are abomination to best austere abstracts visualizers. Leading experts like Edward Tufte suggest they should about never be used. At Quartz, we so acerb abash application pie archive that our chart-building tool doesn’t alike action them as an option.
Why, then, does the pie blueprint persist? In short, bodies adulation circles.
The accuracy is that archive aren’t alone about communicating abstracts effectively. They’re additionally about aesthetics and cartoon in an audience.
In a 2011 article, statisticians Andrew Gelman and Anthony Unwin differentiate amid “statistical graphics” and “information visualization.” Statistical graphics, they explain, are advised to acutely back abstracts to the absorbed reader. By contrast, advice decision “grabs the reader’s absorption and draws him or her into the story.”
It is accurate that bar archive are about consistently bigger as statistical graphics, but because bodies assume to adopt circles to squares, pie archive are generally bigger for advice visualization. In Smithsonian Magazine, Megan Gambino credibility to a array of studies that appearance bodies are added admiring to objects with curves. This may be because change led bodies to accessory aciculate angles with danger, while curves are a assurance of bloom and life.
People aloof can’t advice themselves. The pie blueprint will never die.
