Graph of related ingredients in allrecipe.com’s recipe database. Here’s the study that produced the graphs, and here’s a blog post providing a nice exegesis of the graph: “two main communities fall out, one sweet, the other savory.” (via Food Tech Connect, Hacker News)

Literary Organism, a classic visualization of On the Road by Stefanie Posavec. This post is really just an excuse to link to Stefanie’s portfolio. Everything there is just astounding (including this limited edition of Murakami’s 1Q84).

Talk-o-Meter is an iPhone app that shows how much time in a conversation is taken up by the participants. Right now it seems to work only as a stand-alone app; I would love for this to work with actual phone conversations. Let’s get some deeper metrics in there, too, while we’re at it: when someone calls me, the phone should let me know—based on the caller—how long the conversation is likely to take, what the emotional tenor of the call is likely to be (based on previous sentiment analysis), what topics we’re likely to cover, who I’m most likely to call next, etc.

“[I]t’s ludicrous to make sense of a complex topic like the Iraq War by looking only at the words used to describe the events. Don’t confuse signifiers with what they signify.”
— Jacob Harris in his excellent screed Word clouds considered harmful. A must-read for anyone doing journalism, visualization, text analysis, or generative/appropriative writing.

Dan Zarrella used a simple algorithm to draw a heat map of the optimal link placement for clicks in a tweet. Let’s use analogous technology to find the optimal placement for enjambment in a poem, or the optimal placement for introducing a new character in a novel.

“Surrounding this chain are about 70 word frequency histograms showing the issue-by-issue usage of different terms […]. I used a simple space-filling algorithm to […] stack them so that one histogram begins shortly after another ends. This ended up resulting in some interesting word chains that show how technology has progressed – some that make sense (microcomputer to e-mail) and some what are more whimsical (supernatural to periscope to datsun to fax). Picking out interesting words from all of the available choices […] was a tricky part of the process. I built a custom tool in Processing that pre-visualized the frequency plots of each word so that I could go through many, many possibilities and identify the ones that would be interesting to include in the final graphic.”
— Jer Thorpe on 138 Years of Popular Science (previously). I’m not generally a big fan of word frequency visualizations, but this one works. I like that Thorpe hand-picked the words to include, and that he didn’t intentionally exclude whimsical results.
