Statistical Visualization

Statistical Visualization
For his book The Visual Miscellaneum, David McCandless, along with Lee Byron, had a look at breakups on Facebook, according to status updates. They looked for the phrase "we broke up because" in status updates, and then graphed the frequencies over time. Why they couldn't just look at updates to relationship status, I'm not sure. Notice the peak leading up to the holiday season and spring cleaning. Finally, there's the highlight of Mondays, which you might lead you to believe that people like to call it quits during the beginning of the week. [Information is Beautiful | Thanks, Elise]

37 Data-ish Blogs You Should Know About You might not know it, but there are actually a ton of data and visualization blogs out there. I'm a bit of a feed addict subscribing to just about anything with a chart or a mention of statistics on it (and naturally have to do some feed-cleaning every now and then). In a follow up to my short list last year, here are the data-ish blogs, some old and some new, that continue to post interesting stuff. Data and Statistics By the Numbers - Column from The New York Times visual Op-ed columnist, Charles Blow, who also used to be NYT's graphics director.Data Mining - Matthew Hurst, scientist at Microsoft's MSN, also the co-creator of BlogPulse.Statistical Modeling - We might disagree on certain things, but Andrew's blog is one of the few active pure statistics blogs.The Numbers Guy - Data-minded reporting from Carl Bialik of the Wall Street Journal.Basketball Geek - Like statistical analysis and basketball?

Junk Charts This post is part 2 of an appreciation of the chart project by Google Newslab, advised by Alberto Cairo, on the gender and racial diversity of the newsroom. Part 1 can be read here. In the previous discussion, I left out the following scatter bubble plot. This plot is available in two versions, one for gender and one for race. The story appears to be a happy one: in many newsrooms, the leadership roughly reflects the staff in terms of gender distribution (even though both parts of the whole compare disfavorably to the gender ratio in the neighborhoods, as we saw in the previous post.) Unfortunately, there are a few execution problems with this scatter plot. First, take a look at the vertical axis labels on the right side. I find this decision confounding. The horizontal axis? Here is the same chart with improved axis labels: Re-labeling serves up a new issue. The solution, as shown below, is to shift the vertical gridlines by 5% so that the 45-degree line bisects every grid cell it touches.

Information is Beautiful: You've Been Quango'ed visualisation | News Information is Beautiful on quangos Illustration: David McCandless for the Guardian We all know 'quango' is a dirty word. Like bad fruits, they're useless, extraneous, over-funded non-government bodies that need to be quoshed or squeezed. Right? There are over 1,000 such organisations in the UK. Many face severe cuts and even the axe in the next government spending review on 20th October. Problem is, I don't know what most quangos do. Frustrated by this, I set about researching these bodies and what they did. So here I've: • Visualised every quango that receives over £25m in direct funding from the government • Filtered out exclusively Welsh, Scottish and quangos from Northern Ireland (just to make it manageable) • Described the purpose or role of every quango in plain English (many quangos have arcane names and jargonistic self-descriptions) • Detailed the major quangos to be abolished or 'under review'.

Announcing a California High Speed Rail Station Area Mapping Tool! (Beta Version) | Advanced GIS: Web GIS Topic, Description, and Functionalities Railway to Heaven seeks to buoy the California High Speed Rail Authority’s community outreach efforts through a new web-based interactive mapping tool. The Proposed CAHSR Station Area Study website displays the proposed alignment for California’s High Speed Rail with detailed station area analyses for Los Angeles and Anaheim. At the station area level, this tool displays data on proposed station location, transit intermodality, proximate built environment characteristics, and housing affordability. Users can access information at two scales within the site: state and station-area level. Statewide map featuring alignment information and station area study sites At the station-area level users can display live data from Zillow, Flickr, and Los Angeles County Metropolitan Transportation Authority in addition to published data from the High Speed Rail Authority and Orange County Transportation Authority.
