Isarithmic History: 88 Years of Red-Blue Divide in 1 Minute

By Maria Popova

Data visualization is at its most powerful when it helps illuminate cultural patterns and trends not easily visible, or at least digestible, to the naked cognitive eye. That’s exactly what Duke PhD candidate David Sparks does in this excellent visualization of the isarithmic history of the two-party vote, which captures 88 years of red-and-blue divide, 1920-2008, in just one minute.

More about the process and the data is available on Sparks’ blog.
