Everlasting pie chart

Manuel Lima goes into the history of the pie chart, or rather, circle representations in general. Despite many people poo-pooing the chart type over the decades, it keeps hanging around:

We might think of the pie chart as a fairly recent invention, with arguably more flaws than benefits, in regards to the statistical portrayal of data. However, if we look deep into history we realize this popular chart is only a recent manifestation of an ancient visual motif that carried meaning to numerous civilizations over space and time. A graphical construct of radiating lines enclosed by a circle, this motif is also a powerful perceptual recipe. If we look deep into ourselves we uncover a strong proclivity for such a visual pattern, despite the final message it might carry. As one of the oldest archetypes of the circular diagram, the sectioned circle will certainly outlast all of us, and indifferent to criticism, I suspect, so will the pie chart.

Yep.

Lima wrote a whole book on the use of circles in information design, in case you’re feeling yourself drawn to the shape for some unexplained reason.

Historical data visualization panel

Manuel Lima hosted a free online panel with Michale Friendly and Sandra Rendgen historical data visualization. It already happened, but you can listen to the archived version:

Human beings have been involved in the visual representation of information for thousands of years. While some books on Data Visualization go as far back as the 18th century, to what’s considered to be the golden age of information graphics, the history of the practice is much deeper. The participants on this panel have spent years exploring key characters and major contributions to the field of Data Visualization over many centuries. We will be discussing ancient visual metaphors, the challenges of doing research in this area, what we can learn from the past, and many other topics.
