I See What You Mean

Infographics are clearly having a cultural moment. They have become pervasive in newspapers, magazines, blog posts, and viral tweets; they appear on television and in advertising, in political campaigns and at art openings. As a Google search term, “infographic” has increased nearly twenty-fold in the last five years. Yet infographics have been popular, in one form or another, for centuries. The source of their power isn’t computers or the Internet, but the brain’s natural visual intelligence.  Gareth Cook , the editor of Best American Infographics 2013 , has put together a short but true summary of the history of information graphics. (Many of you who see this blog may know most of it already.) His striking lede recounts how much Abraham Lincoln valued his "slave map" (featured in an earlier blog post ). Lincoln's reliance on the shades of gray throughout the Confederacy made an enormous difference in his Civil War decision-making.  Fortunately it's rare that mos

"A Tour Through the Visualization Zoo" is a fantastic introduction to some attractive and sophisticated new visualization formats. The article and illos were put together by Stanford's Jeffrey Heer, Michael Bostock, and Vadim Ogievetsky. Heer is an HCI/visualization genius whose journal articles I've been following with interest; Bostock is the whiz behind the D3 archive of javascript code for visualization. Run, don't walk. It's great.

Another in our occasional series on Where The Numbers Come From : What more could the aspiring info-interpreter want than a Comprehensive Knowledge Archive Network ? Hosted/maintained/curated by the folks at the Open Knowledge Forum , it provides more than 350 data "packages" (from the Airborne Antarctic Ozone Experiment to Yosemite National Park ) and code that are "free for anyone to use and reuse." Some packages contain video or podcasts, others static images, still others scientific data. The mix of media means there's something to entice analysts of all bents. For my part, since I am a lifelong Bardbrain (I once wrote a thesis on metaphorical structure in the language of Shakespeare's plays), I find this subsite especially intriguing. I'll try to whip up a Shakespeare-related visualization and post it here soon.

As part of his larger mission of promoting "fact-based" public health policy, Swedish physician Hans Rosling founded Gapminder.org , which aims to make world health data available and understandable to everyone. Back in 2006, Rosling gave a well-received TED presentation on the principles of Gapminder, showing, among other things, relative historical changes in life expectancy and GDP. ( He spoke again in 2007. ) Rosling acknowledges that there are some small flaws and inconsistencies with data derived from all these different sources, but believes that the comparative results are far more significant. Check out the vast difference between Mauritius and Congo in income per person and life expectancy (shown on the Gapminder site and in the '06 presentation); consequently, says Rosling, using the term "sub-Saharan Africa" to describe both of these countries is vague to the point of uselessness. His point: The more easily data and details can be visualized and co
