Edward Tufte’s Slopegraphs
This is pretty darn cool. Charlie Park details Slopegraphs, a chart format that Edward Tufte developed for his book, The Visual Display of Quantitative Information. Unlike sparklines, another chart format Tufte developed, these never really took hold.
Back in 2004, Edward Tufte defined and developed the concept of a “sparkline”. Odds are good that — if you’re reading this — you’re familiar with them and how popular they’ve become.
What’s interesting is that over 20 years before sparklines came on the scene, Tufte developed a different type of data visualization that didn’t fare nearly as well. To date, in fact, I’ve only been able to find three examples of it, and even they aren’t completely in line with his vision.
It’s curious that it hasn’t become more popular, as the chart type is quite elegant and aligns with all of Tufte’s best practices for data visualization, and was created by the master of information design. Why haven’t these charts (christened “slopegraphs” by Tufte about a month ago) taken off the way sparklines did?
Well worth a read if you care about stuff like this.
Edward Tufte Profile
Joshua Yaffa profiles Edward Tufte, one of my personal heros, for The Washington Monthly.
After the publication of Envisioning Information, Tufte decided, he told me, “to be indifferent to culture or history or time.” He became increasingly consumed with what he calls “forever knowledge,” or the idea that design is meant to guide fundamental cognitive tasks and therefore is rooted in principles that apply regardless of the material being displayed and the technology used to produce it. As Tufte explains it, basic human cognitive questions are universal, which means that design questions should be universal too. “I purposely don’t write books with names like How to Design a Web Site or How to Make a Presentation,” he told me.
