The Joy of Stats with Hans Rosling

November 30, 2010 to Statistics, Visualization • Share on Twitter • Comments (22)

The Joy of Stats, a one-hour documentary, hosted by none other than the charismatic Hans Rosling, explores the growing importance of statistics:

[W]ithout statistics we are cast adrift on an ocean of confusion, but armed with stats we can take control of our lives, hold our rulers to account and see the world as it really is. What's more, Hans concludes, we can now collect and analyse such huge quantities of data and at such speeds that scientific method itself seems to be changing.

From the description, it sounds like they'll touch on Crimespotting by Stamen, Google Translation, among other data-driven projects. Whatever they cover, it's bound to be interesting with Rosling at the front.

How do people use Firefox?

November 30, 2010 to Data Sources, News • Share on Twitter • Comments (3)

Mozilla Labs just released a bunch of anonymized browsing data for their open data visualization competition:

This competition is based on Mozilla's own open data program, Test Pilot. Test Pilot is a user research platform that collects structured user data through Firefox. All data is gathered through pre-defined Test Pilot studies, which aim to explore how people use their web browser and the Internet.

There are two datasets in various formats. The first is browsing behavior from 27,000 users, including on/off private browsing that we saw a few months ago. The second dataset is from 160,000 users and is on how they actually use the Firefox interface.

Additionally, both sets have survey answers to questions like "How long have you used Firefox?" which could make for some fun and interesting breakdowns.

The deadline is December 17.

Statistics vs. Stories

November 29, 2010 to Statistics • Share on Twitter • Comments (2)

Professor of Mathematics at Temple University, John Allen Paulos describes the differences between statistics and stories:

[T]here is a tension between stories and statistics, and one under-appreciated contrast between them is simply the mindset with which we approach them. In listening to stories we tend to suspend disbelief in order to be entertained, whereas in evaluating statistics we generally have an opposite inclination to suspend belief in order not to be beguiled.

And he concludes:

The focus of stories is on individual people rather than averages, on motives rather than movements, on point of view rather than the view from nowhere, context rather than raw data. Moreover, stories are open-ended and metaphorical rather than determinate and literal.

Which way do we go when we start telling stories with data?

Something for you leading into the Thanksgiving weekend. Enjoy this short video (below) by Amy Thornley, which she made for smile for london. It was animated frame-by-frame in Excel. I look forward to when someone makes this an actual game. That way you could play it at the office, and it would look like you're working when you pause it.

In case you missed it, Girl Talk recently released his fifth album All Day, which samples from 372 songs. Essentially, it's an album of mashups, so together, samples from multiple songs combine to make a single song. @brahn shows what samples are playing at any given time as you listen to the album. Press play, and the current samples highlight.

How Twitter users balanced the budget

Political science PhD candidate David Sparks has look at the evolution of the two-party vote:

Using county-level data, I spatially and temporally interpolated presidential vote returns for the two major party candidates in each election from 1920-2008. The result illuminates the sometimes gradual, sometimes rapid change in the geographic basis of presidential partisanship.

Target for charting excellence

The scales for what qualifies as pretty and useful change depending on the application and purpose, but you always aim for the same quadrant. The best data graphics come from those who are able to find the right balance between aesthetics and utility.

A world of tweets

November 18, 2010 to Mapping • Share on Twitter • Comments (2)

We've seen this sort of thing before, with tweets mapped and such, but the recent A World of Tweets by Frog Design is nicely executed (in HTML5).

A World of Tweets is all about playing with geography and bits of information. Simply put, A World of Tweets shows you where people are tweeting at from the past hour. The more tweets there are from a specific region, the "hotter" or redder it becomes.

You can toggle between a few different views such as smokey or heatmap, or outline or satellite view, but the highlight has gotta be the 3d view. Unfortunately, I don't have any red and blue paper lens glasses on me. Dang it.

Defining neighborhoods with map scribbles

November 18, 2010 to Mapping • Share on Twitter • Comments (6)

TenderMaps brings an informal approach to highlighting the parts of neighborhoods:

We wanted to move from the static and singular, toward more dynamic, subtle definitions of neighborhoods, definitions emphasizing the nuanced communities and personal experiences that really shape a neighborhood's boundaries. We wondered how we could we harness the implicit mental maps people actually use. What would happen if we defined a neighborhood by the way we moved though it, or by the places we loved in it?

In this first iteration, the creators walked around the Tenderloin in San Francisco, and asked residents questions about their neighborhood and to sketch on a paper map. The sketches were scanned to make a browsable map, including backstories of each scribble.

The proof of concept is still rough, and uber slow in Chrome, but it should be able to see how useful this might be. It's much more personal than the markers we are used to seeing and could be a way for non-tech people to see their community in a tech way.

What generation do you belong to?

November 17, 2010 to Infographics • Share on Twitter • Comments (16)

In this interactive, USA Today guesses your age, based on what influenced you as a teenager:

The year you were born partly determines what generation you belong to, but so do your cultural experiences. The chart below shows the offset from birth years to one's teenage years — when people are most influenced by the world around them — and the music, movies, TV, news, fashion, technology, toys and sports of those eras.

Simple and entertaining. I took the quiz twice, and it was different each time. It was one year off both times, so dead on when you take the average. What generation do you belong to?

R is the need-to-know stat software

November 17, 2010 to Software, Statistics • Share on Twitter • Comments (24)

This Forbes post on the greatness that is R is being passed around by every statistician and his mother today.

It's not that this type of analysis wasn't possible before — statisticians have existed, and commercial software has been available to support them, for decades. The fact that R is free to use, free to modify, and its source is open to view, extend and improve means students, stock traders-in-training and fantasy football junkies can familiarize themselves with the software. They can write programs against it. They're likely to continue that usage into their professional lives. When they share their work, the community, down the line, benefits. And the virtuous cycle strengthens.

What's your favorite (graphical) use of R?

Why network visualization is useful

November 17, 2010 to Network Visualization • Share on Twitter • Comments (2)

AT&T Labs' Infoviz research group describes network graphs and their many uses:

There is information in the connections. A glance is enough to identify nodes with the most links, nodes straddling different subgroups, and nodes isolated by their lack of connections. Corporations might look at a graph to verify that marketing and sales are communicating, urban planners to monitor the interconnectedness, or isolation, of neighborhoods, biologists to discover interactions between genes, and network analysts to monitor security.

And on aesthetics:

Aesthetics is important not so much for looks—though some visualizations can be stunning to look at—but for readability. Links that intersect and nodes that overlay one another result in poor readability, and graph visualization programs work hard to minimize the number of link intersections and give enough whitespace around each node to make it stand out from its neighbors.

Format and clean your data with Google Refine

November 16, 2010 to Software • Share on Twitter • Comments (12)

When we first learn how to deal with data in school, it's nicely formatted and fits perfectly into a rectangular spreadsheet. Then when we start to deal with real data, we find missing values, inconsistencies, and for some reason it doesn't plug straight into our software. What the heck?

The caveman way to fix this problem is to open Excel and manually edit everything. Some ad hoc code can often fix your problems, but still that takes time and can be a pain. Google Refine, the Googley evolution of Freebase Gridworks, can help you.

The very first NYT election map

November 15, 2010 to Mapping • Share on Twitter • Comments (5)

Matthew Ericson, deputy graphics director of The New York Times, dug through the archives to find the first occurrence of an election map in the paper, in 1896:

The speed with which the results made it into print boggles the mind given the technology of the day (especially considering that in the last few elections in the 2000s, with all of the technology available to us, there have been a number of states that we haven’t been able to call in the Wednesday paper).

What a beaut. That day, the paper cost 3 cents.
