Edward Tufte’s ‘Slopegraphs’

Great piece on data visualization by Charlie Park:

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.
