Why not use all the senses to understand data? It would be interesting to layer in a comparison set of data and hear how they interact.
What we’d like to see next: odor graphics. A market graph that stinks when it sinks.
I came across this visually arresting depiction of gun murders today, thanks to a tip from my friend, Kimball. It was created by the folks at Periscopic, whose mission is to “do good with data”. The animation packs a punch, and when it’s finished, you have a number of options for diving into the data, including getting a sense of the individuals affected.
The arcs in the graphic show how long the murdered person might have lived, trying to give a sense of “stolen years”. I was a bit skeptical when I saw some of the lines showing a life expectancy in the 90s, but reading the notes on methods and sources, I see that each individual line is based on a the age distribution of deaths (not the average life expectancy). Meaning that there would logically be a few people that would make it into their 90s (and some that would die at 50).
I know this is a topic on a lot of minds right now. Not sure where I come down on gun control, but I do find that this exploration raises a lot of questions in my mind. Like a good data visualization should.
In an interesting coincidence, the original dataset was researched by Jerome Cukier, who is helping me with a project right now.
Here’s a nice interactive example of making data friendly to the average human. What country would you like to live in? With the OECD Better Life Initiative, you can pick what you care about (Environment, Work-Life Balance, Health, etc.) and see which countries rise above the rest. Another interactive wonder from the brain of Moritz Stefaner. He’s the same designer who created the Notabilia Wikipedia project that I posted about a while back. Looks like it’s time for me to move to Australia.
Palo Alto Networks launched the data visualization that we created yesterday with the release of their Application Usage & Threat Report. It’s a depiction of network traffic collected from 3,000+ organizations. The visualization gives you a sense of the applications that eat up the most bandwidth and represent the greatest risk. There are many ways to slice and filter the data, facilitated by the capabilities of the d3.js library. Many thanks to Jérôme Cukier for his coding expertise to bring the concept to life.
Another piece of the project was to create this related infographic.
I very much enjoyed delving into the world of moving spheres. What is it about us that is drawn toward playing with bubbles? Looking forward to more projects like this.
Came across this fascinating interaction from the New York Times, doing research for a client project. It was interesting just as a static image with a few rollovers, but then I clicked some of the links up top (types of spending, changes) and things started flying.
I like how it invites interaction. The playfulness of the motion may be a little distracting from the data, but I think it does make it more “sticky”. Try clicking back to the “all spending” tab after exploring the others – interesting to see that the individual bubbles don’t exactly fall back into their original places. I guess the budgeting process is messy like that.
Thanks to Jim Vallandingham for the link.
Fast Company magazine recently featured this beautiful rendition of the ocean’s currents on their blog. It was put together by the visualization geniuses at NASA’s Scientific Visualization Studio and can be viewed in a variety of formats (including an iPad app).
It’s worth downloading one of the high resolution video formats from the NASA site.
I recently discovered Data Stories, a podcast devoted to data visualization hosted by Moritz Stefaner and Enrico Bertini. I have been listening daily in the car on my way from here to there and have made it up to Episode #7 – Color. I think I’ve found my tribe.
Hans Rosling is an entertaining and compelling presenter. He uses the now-Google-owned Public Data Explorer technology (developed by his organization Gapminder), to take you on a journey testing your concept of the developing world.
I recommend watching him in this TED talk delivered to the U.S. Department of State:
Stumbled across this interesting interactive work of Ben Fry’s – a great example of visualizing large amounts of data in a cohesive way. He has visually shown all the changes made by Charles Darwin to his classic On the Origin of Species over six different editions. The book went from 150,000 words to 190,000 by the sixth edition, with some interesting edits along the way (including a significant addition to the closing paragraph).
I think what I like most about it is the clear illustration of how the scientific process can lead to continual learning and refinement of ideas. Keep your mind open. Take a look.
A data-heavy project I’ve been working intensely on the last week or so was released yesterday. It’s a statistical review of corporate governance practices since Sarbanes-Oxley, done by the law firm Fenwick & West.
I enjoyed wrestling with Excel and Illustrator to create histograms, box and whisker plots and a few original creations. And the client was great to work with – detail-oriented, appreciative of good design, understanding of complexity. You can download the full report here: Corporate Governance Practices and Trends
It’s amazing how much more understanding you get out of a well-designed visualization than a spreadsheet of numbers. We went from something like this:
Is it strange that I love graphs so much?
Here’s one person’s list of the “12 Great Visualizations that Made History“. I’m in general agreement, although I think #11 (the gold plaque on the Pioneer 11 spacecraft) can’t count until we hear back from the aliens.
Reading the raw data, or even a well-written description, doesn’t have the same impact on understanding as an effective visualization. Like in this famous image of how to pack a slave ship (#2 on the list):
Several people have pointed me to a well-crafted data visualization by Pitch Interactive showing data for U.S. drone attacks in Pakistan. Like a good visualization should, it answered some questions and sparked a few more. To answer some of the questions that came to me, I put together this graphic that gives another angle on the same data.
The bands of color represent total deaths by victim category. From the notes on Pitch Interactive’s site, it sounds like the victim categories can be a little fuzzy, with the definition of “other” depending on who is doing the defining. The Obama administration calls an able-bodied adult male a military combatant if it has not been proven that they are a civilian – here those are classified as “other”. The death totals are approximations too, as many reports include a range (e.g. “6-10 people were killed in a drone attack…”).
Assuming the primary targets of the drones are the so-called “high-profile” combatants, with other combatants as secondary targets, I calculated percentages comparing all civilian deaths (children + civilians) to non-civilian deaths (high-profile + other) to see how often the drones were on target. Those are the dotted lines. This data is up to date through a few days ago (March 22, 2013). I encourage you to check out the interactive visualization here: drones.pitchinteractive.com
This week, my sister tipped me off about The Atavist, a new take on multi-layered storytelling via iPhone or iPad apps (also available on Kindle and Nook). Threestory Studio got its name in part because of my interest in telling stories visually, so I was intrigued to see what The Atavist had to offer.
One of the first things I discovered was a rich infographic showing the events leading up to the fall of the regime in Egypt. It combines a timeline of events with web traffic data and social media engagement in Egypt.
It wasn’t immediately clear what the black bars rising from the bottom were – they appear to indicate numbers of people involved in protests or revolutionary activities. Otherwise, this graphic receives high marks.
Just discovered LinkedIn InMaps today. A good example of interactive information graphics that can lead to discovery. Interesting to find the connections that bridge groups. Like the “I didn’t know Tony knew Larry!” moment.
This fact would have been discoverable just browsing through my connections on the standard LinkedIn site, but seeing the whole network mapped in one place removes a lot of barriers to this kind of discovery.
The zoomed-out view shows an accurate picture of my circles – the smaller clearly defined orange is a networking group I’ve been closely connected to for over a dozen years, the dense multicolored cluster opposite are my various church connections, with family mixed in. In between are various work and school connections that are scattered and less well-defined.
It’s not hard to create your own. Try it here. I’m curious to see what other people’s networks are shaped like.
Moritz Stefaner is a freelance designer in Europe creating some beautiful and data-rich visualizations. I came across his Notabilia project yesterday, after following a lead from someone at The Leonardo.
It maps the collective editing process for Wikipedia articles up for deletion. Right-leaning red segments are votes to delete; left-leaning green ones are votes to keep. The shape of each branch is an excellent mapping of the shape of the discussion. And the collection of 100 branches makes a lively, energetic whole that begs to be explored.
Projects like this excite me about the power of information design to bring things to light that aren’t easily discernible any other way.
“Things change. Now what?”
That’s the tagline for a new website examining statistical indicators of how life in the U.S. has changed over the last few decades: startlingstats.com. Threestory Studio created all the graphics and designed the site. The aim of the site is to wake people up and promote dialogue about life “as we know it”. I use quotes there because who is “we” and what do “we” really know are all part of the debate. I hope you’ll take a look at the site and leave a comment or two.
Threestory Studio’s second data visualization project with Silicon Valley law firm Fenwick & West was released to the public this week. This report looks at trends in venture-funded deals in the life sciences.
Though not as extensive or complex statistically as the first one (Corporate Governance Practices and Trends), this one presented some interesting challenges in presenting data clearly, accurately and concisely. I’m happy with the results.
Thanks to my watchful nephew Christopher P. for pointing me back to my Alma Mater to see this nice interactive visualization linking college majors to career choices.
It was put together by Williams College math students and their professor using CIRCOS visualization software. Rolling over the thumbnails allows you to isolate the paths from individual majors to careers. Nice use of colors to organize majors within larger groupings. I majored in Music (Composition) – not sure if I’m represented by the path to arts/entertainment, writing/communication or other. I’ve always preferred to be uncategorizable.
I’m guessing Williams, as a liberal arts school, may have a more evenly distributed set of careers than some other schools. I’d be interested to see how this same distribution looks for other schools of different types and sizes.
Check out this interactive look at the scale of the universe. Puts things in perspective, from a Planck length to the observable universe:
I’m impressed with two things about the World Bank’s approach to data: first, their commitment to openness in sharing data with the world, and second, their devotion to data visualization. They have also done a nice job inviting exploration with the way they have organized their data website.
Interesting to see that the mortality rate for children under 5 in the US is about 37% higher than the average of high income OECD countries.
And the US spends way more on healthcare than almost any other country in the world. Maybe we’re not spending it on the young.
Note: The World Bank is the source of data for the sample I gave a while back using the Google Public Data Explorer.
Reading Edward Tufte’s “Envisioning Information“, I came across a simple graphic, originally published in the Chinese mathematics treatise Zhou Bi Suan Jing (or Chou Pei Suan Ching) that impressed with its simplicity. It’s a visual, geometric way of proving the Pythogorean Theorem that was published around 2,000 years ago. If you compare it with Euclid’s proof, this picture is worth about 500 words.
Any mathematicians out there know that there are many ways to prove the theorem attributed to Pythogoras – I like the simple elegance of this one. Here’s my redrawing of the Chinese original.
With the presidential election fast approaching, interest in the predicted outcome is high. I’m impressed by detailed data graphics on Nate Silver’s FiveThirtyEight blog for the New York Times, not only for their clarity but for his thoroughness in examining the data.
I guess we’ll see about the accuracy of all these predictions after November 6.
Trust the Olympics to inspire some innovative data visualization. Thanks to friend Peter F. for the tip on a nice series of visualizations from The New York Times that compare today’s winning sprinters, swimmers and jumpers with past medalists.
Interesting to see the steady march forward over the years in swimming and sprinting.
The promised infographic résumé tool that I mentioned a few posts back has launched at Vizualize.me. It’s a customizable infographic interpretation of your LinkedIn profile, to which you can add skills and other experience. Using LinkedIn to populate the infographic gives a jumpstart to the process. Seeing work experience in a timeline makes a lot of sense, though the scale of the education timeline differs from work experience in a way that gives a distorted view. See my full infographic CV:
I was thinking about the visual display of uncertainty today and came across this nice example from a weather site in Norway. It shows the probable range of future temperature and precipitation levels for the city of Oslo. This is a good solution for something I’ve puzzled about for a while: When I hear that there’s a 30% chance of rain, I’m always asking myself “a 30% chance of how much rain?” A 30% chance of a light sprinkle is a much different forecast than a 30% chance of a deluge.
It would be interesting to know what factors go into the variability of the forecast. I imagine that the further out in time the forecast is, the more uncertain it would be, but there are obviously other factors that affect probability as well.
I also like their “detailed meteogram” with an hour-by-hour view of precipitation, temperature, and pressure, enhanced by an elegant indication of wind speed and direction, and topped off with an artful visualization of cloud cover.
Makes me proud to be 1/8 Norwegian.
First impression: it’s a whole lot more windy over the oceans than it is over land. Intuitively obvious (even to the casual observer, as an old friend used to say), but the visualization drives the point home instantly. Now, what happens if we combine global wind data with ocean current data? It would be interesting to see how they interact.
Thanks to Andy Kirk at Visualising Data for pointing this out.
Looks like you may soon be able to create a visual version of your resume in “one click” with the help of vizualize.me. Resumes are certainly fertile ground for visual rethinking, and what job applicant doesn’t want their resume to stand out from the pack?
We’ll see how much customizing is possible once they launch. With the diversity of individual experiences and the differences among job opportunities, it seems like customized options are a must — I know I wouldn’t send the same resume to two different potential employers. If this catches on, it may make it easier for employers to compare resumes, but that would lead us back to people wanting to differentiate. Maybe that’s where visualize.me starts up-charging for higher levels of customization. Sounds a little like Sylvester McMonkey McBean and the racket he pulled off on the Sneetches. Are there stars upon yars?
