IV and the news: Iran election data

As thousands and perhaps millions take to the streets in Tehran to protest Iran's (alleged) election fraud, the UK's Guardian goes nitty-gritty, posting a data set of polling results.*

The paper ends its report thus: "Can you do something with this data? Please post us your visualisations and mash-ups below or mail us at ."

Its story also links to data maps from and Iran Tracker. (Elsewhere at Fivethirtyeight, Nate Silver considers the statistical analysis that ostensibly proves the election was rigged -- in other words, the basis of the protestors' unrest.)

Here's the direct link to the election data, in case anyone out there feels like having a go at it; I hope I'll have some time to muck around with it myself.

*Per the story: "The figures we've uploaded are, as far as we can work out, the official totals, so you should be safe using them." Take that as you will. Note also that if you read Farsi, you can get the stats straight from the mullah's mouth here.

UPDATE ON THE DATA (UPDATA?): Pollster runs a roundup of news items in which people point out that certain aspects of the official election stats are, er, unlikely to occur naturally. No infographics, but lots of interesting analysis nonetheless.


  1. If you're interested in infographics, I suggest my visualization page, which has graphics for all three of the sources listed by Pollster.

Recommended: a new review "zoo"

"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.

Blast from the past: a 1974 data treatise by Edward Tufte

Back in 1974, Yale poli-sci professor Edward Tufte published a slim volume called Data Analysis for Politics and Policy (Prentice-Hall, $3.95). The book in its entirety is available for free download (PDFs) at Tufte's website, accompanied by a contemporary review from the Journal of the American Statistical Association. More than 30 years later, the review amuses me with its restrained praise of the perspective that would eventually make Tufte a Major Figure (and a minor fortune):
Tufte puts residual plots to good use to gain understanding of a data set, and he shows how finding outliers gives the analyst hints about the inadequacy of a statistical model... The discussion of graphical techniques in general is quite good... A brief but compelling discussion of the "value of data as evidence," with regard to the interpretation of nonrandom samples, is presented. If you happen to have a spare 48MB lying about, DAPP's worth a download.
