• Explore Your del.icio.us Tags and Bookmarks On 6pli

    March 4, 2008  |  Statistical Visualization

    Santiago, who I met at the Visualizar workshop, forwarded me his work on the visualization of del.icio.us tags and bookmarks called 6pli. Normally, I'm not a big fan of network diagrams, because I always seem to get lost in all the nodes and edges cluttering up the place. I feel differently about 6pli though.

    6pli sets itself apart with really smooth, responsive interaction and three views - elastic net 3-d, elastic net 2-d, and circle 2-d. All three views rely on a metric of tag-similarity. So the more co-tags that a single tag has with its neighbors, the closer the tags will be in proximity.

    Was that confusing? OK, it'll be more clear with pretty pictures.

    Elastic Net 3-D

    The elastic net 3-D (pictured above) shows tags and bookmarks in a 3-dimensional view. Tags are in rectangles and bookmarks are circles. A bookmark (or circle) will be closer to another bookmark (or circle) if it has more tags in common. Similarly, if a tag is often grouped with other tags, it will appear closer to that group. Click on a tag, and a list of bookmarks show up on the right.

    The cool part is when you start playing with the 3-D network blobby. You can rotate it like a globe and the movement is controlled by spring action. The visualization's response is immediate and really smooth with nice transitions from one view to the next, unlike this paragraph.

    Elastic Net 2-D

    Elastic Net 2D

    The 2-dimensional view is the same principle as the 3-D. The only difference is the 2-D is a projection of the 3-D view onto a flat plane. Smooth interaction still applies here.

    Circle 2-D

    Circles 2D

    Finally, the circle view arranges tags and bookmarks into their del.icio.us bundles. Each circle is divided homogeneously and the radius of the circle can me manually modified.

    One thing I would recommend for the beta release is some kind of input to type in a tag or the name of a bookmark. Right now, the starting point feels kind of random, but if I could specify where I wanted to explore, I think the viz would be that much more useful.

  • Can We Improve this Graphic Showing History of Bipartisan Senate?

    February 28, 2008  |  Statistical Visualization

    David forwarded me his graphic on the modern two party system in the United States senate which essentially shows the senate's bipartisanship over time. It made me happy to see someone in political science using R, playing around with data, and taking a stab at creating a useful graphic.

    Improving the Graphic

    While the graphic is indeed useful, I think there are some things that could make it even better. Here are thoughts that I sent to David.

    • I wasn't immediately sure what each visual cue represented e.g. size of state abbrev. until I reached the bottom. It might be worth making the annotation more prominent either by position, size, or color or all three.
    • To me, the congress numbers don't matter so much, but that just might be I don't have a lot of learning on the history of American government.
    • I'm wondering if there's some way to make the labeling of the years more concise? If you just labeled with the first year of the two-year term, would it be obvious that you're describing a two-year term? What if you took away the alternating gray background and just made it all white and then had a bar timeline-type thing on top (and bottom)?
    • What if you tried to use a color scheme? I mean, you have the red and blue for the reps and dems (which I think is right), but the gradient for the senate counts turns very bright pink and purple which doesn't go too well. Then there's the cyan, yellow, and green which doesn't seem to have any specific significance other than each color represents something. What I mean is... is there a reason you chose those colors?
    • It might be worth making the annotations bigger so that you don't have to "zoom in" to read.
    • I think I would make the median lines a bit more prominent, but that's just me.
    • There's a lot of cool stuff getting represented here, and I wonder if anything might benefit as a separate graph. Would this benefit at all as a series of graphs instead of one large graphic?

    Now It's Your Turn

    So that's my opinion. What do you think? Judging from our FlowingData Facebook group (which I'm happy to see is growing), we have a very diverse bunch from design, statistics, computer science, and some other areas, so I'm eager to hear what the rest of you think about this visualization.

  • Visual Website Analytics in Video Game Format

    February 27, 2008  |  Visualization

    Visitorville screenshotFor a while now, I've been interested in how we can apply interaction principles of video games to visualization and exploratory data analysis (although admittedly, gaming is still a very foreign concept to me). Visitorville is an example of how the fun of video games can be applied to analytics. It looks a lot like the awesome classic SimCity (whose source code was recently released, by the way).

    VisitorVille applies video game principles to help you easily visualize and better understand your web site traffic statistics.

    It's easy: each building represents a web page; each bus a search engine; and each animated character a real visitor to your site.

    Just paste our tracking code into your web pages, then launch VisitorVille for Windows to analyze your stats, watch your traffic in real time, provide Live Help, track your PPC campaigns in real time -- and more.

    Using our unique Virtual VCR, you can even play back traffic from any day or time, at any speed.

    Learning From Video Games

    We certainly have a lot to learn from video games -- interaction, user engagement, graphics, and fun. Seriously, statistical visualization could stand to have a little bit 'o fun tossed in. At least that's what I tell my wife when I try to convince her to buy me an Xbox 360.

    Somewhat related note -- there was an interesting talk at Journalism 3G on using video games to tell stories, which I'll be discussing some time in the near future once I get all my notes together.

  • IBM Visual Communications Lab and Stamen Design Are at the NYC MoMA

    February 26, 2008  |  Visualization

    Congratulations to two of my most favorite visualization / design groups - IBM Visual Communications Lab and Stamen Design - who officially now have their work featured at the Museum of Modern Art in New York. Really incredible and well deserved.

    From this past Sunday to May 12, VCL's History Flow and Thinking Machine and Stamen's Cabspotting are featured in Design and the Elastic Mind.

    Design and the Elastic Mind

    The exhibition will highlight examples of successful translation of disruptive innovation, examples based on ongoing research, as well as reflections on the future responsibilities of design. Of particular interest will be the exploration of the relationship between design and science and the approach to scale. The exhibition will include objects, projects, and concepts offered by teams of designers, scientists, and engineers from all over the world, ranging from the nanoscale to the cosmological scale. The objects range from nanodevices to vehicles, from appliances to interfaces, and from pragmatic solutions for everyday use to provocative ideas meant to influence our future choices.

  • What Impact Does Our Country Have on Climate Change?

    February 21, 2008  |  Mapping

    BreathingEarth is an animated map that represents death rate data from September 2005 and birth rate data from August 2006 compiled by the World Factbook and 2002 carbon dioxide emission rates from the United Nations. The frying sound is kind of a nice touch.

    Pretty But Not Very Useful

    I think that BreathingEarth, like many maps before it, communicates an important point (in this case, CO2 emissions), but doesn't particularly do a good job of showing it. I watched BreathingEarth for a few minutes, but I didn't get much of a sense of what country had more deaths, had more births, or created more CO2 emissions. It's one those projects when a statistician could have lent a useful hand.

    So to answer the question - What Impact Does Our Country Have on Climate Change? - I'm not sure. It is a pretty map though.

  • Is an Animated Transition From a Scatter Plot to a Bar Graph Effective?

    February 20, 2008  |  Statistical Visualization

    Statistical graphics are kind of stuck in a static funk where you create a plot in R, Excel, or whatever, and you can't really interact with it. If you want another graphic, you manually create it. Hence, Jeffrey Heer and George G. Robertson investigated the benefits of using animation in statistical graphics. Continue Reading

  • How to Read (and Use) a Box-and-Whisker Plot

    February 15, 2008  |  Statistical Visualization

    Box-and-Whisker Plot LessonThe box-and-whisker plot is an exploratory graphic, created by John W. Tukey, used to show the distribution of a dataset (at a glance). Think of the type of data you might use a histogram with, and the box-and-whisker (or box plot, for short) could probably be useful.

    The box plot, although very useful, seems to get lost in areas outside of Statistics, but I'm not sure why. It could be that people don't know about it or maybe are clueless on how to interpret it. In any case, here's how you read a box plot.

    Reading a Box-and-Whisker Plot

    Box-and-Whisker Plot ExplainedLet's say we ask 2,852 people (and they miraculously all respond) how many hamburgers they've consumed in the past week. We'll sort those responses from least to greatest and then graph them with our box-and-whisker.

    Take the top 50% of the group (1,426) who ate more hamburgers; they are represented by everything above the median (the white line). Those in the top 25% of hamburger eating (713) are shown by the top "whisker" and dots. Dots represent those who ate a lot more than normal or a lot less than normal (outliers). If more than one outlier ate the same number of hamburgers, dots are placed side by side.

    Find Skews in the Data

    The box-and-whisker of course shows you more than just four split groups. You can also see which way the data sways. For example, if there are more people who eat a lot of burgers than eat a few, the median is going to be higher or the top whisker could be longer than the bottom one. Basically, it gives you a good overview of the data's distribution.

    That's all there is to it, so the next time you're thinking of making a bar graph or a histogram, think about using Tukey's beloved box-and-whisker plot too.

  • Mapping Manhattan’s Skyscraper Districts Through Time

    February 14, 2008  |  Mapping

    Manhattan Timeformations looks like a series of interactive schematics from a video game, but really it's a computer model that allows you to look at the relationships between the developments of the lower Manhattan skyline and other urban factors like farms, urban renewal, subways, and commercial zones. The visualization provides different views in the form of the traditional 2-dimensional map views as well as rotations, fly-throughs, and layers.

    It's nice to step out of that Google mashup look every once in a while.

  • NSF Science and Engineering Visualization Challenge

    January 31, 2008  |  Visualization

    The National Science Foundation is running their annual Science and Engineering Visualization Challenge.

    Some of science’s most powerful statements are not made in words. From the diagrams of DaVinci to Hooke’s microscopic bestiary, the beaks of Darwin’s finches, Rosalind Franklin’s x-rays or the latest photographic marvels retrieved from the remotest galactic outback, visualization of research has a long and literally illustrious history. To illustrate is, etymologically and actually, to enlighten.

    You can do science without graphics. But it’s very difficult to communicate it in the absence of pictures. Indeed, some insights can only be made widely comprehensible as images. How many people would have heard of fractal geometry or the double helix or solar flares or synaptic morphology or the cosmic microwave background, if they had been described solely in words?

    To the general public, whose support sustains the global research enterprise, these and scores of other indispensable concepts exist chiefly as images. They become part of the essential iconic lexicon. And they serve as a source of excitement and motivation for the next generation of researchers.

    They've been accepting submissions since September of last year and will continue to do so until May 31, 2008. The rules are pretty wide open with last year's winners in the area of photography, illustration, and interactive and non-interactive media. Basically, it's whatever you want it to be. The winners will be published in the the journal Science, and one of the winning submissions will get to be on the cover of the prestigious journal.

    Virgil Griffith has created a series of graphs called Books that Make You Dumb. He correlates top books on FaceBook by school and the corresponding schools' average SAT scores. Notice Freakonomics is pretty far to the right. Nice.

    The graphs are of course aren't really that statistical nor are they especially beautiful, but hey, just take it for what is it, and it's kind of amusing. Plus, it's a good example of how you can use data from different sources to find something interesting.

  • 6 Influential Datasets That Changed the Way We Think

  • How a Trip to the Dentist Got Me Thinking About Open Data

    January 22, 2008  |  Visualization

    Warning: Tangent ahead, but I promise, there's a point.

    About a year ago, I went to my 6-month teeth checkup, and the dentist told me that I had a cavity on the bottom back left and another on the bottom back right. Since I was about two years overdue for a checkup (and didn't floss every day), I wasn't surprised.

    One week later, I was back to get my fillings. I sat down in that terrifying chair that looks like something aliens use to probe specimens. The drilling began.

    My teeth are really sensitive, so no matter how many shots of novocaine she injected (3 or 4), I still felt pain. Here's how it went with the first filling. She drilled. I winced. She stopped. We took a short 1-minute break. She drilled. I winced. We took a break.

    We went on like that for about 20 minutes -- all the while she kept telling me it was a tiny cavity and that it shouldn't hurt. Yeah, OK, whatever. Maybe if she actually stuck the needle in the nerve and not just some random place in my gums, it would have worked.

    Anyways, she finally finished and suggested we put off the second filling until the next visit in six months. I thought to myself, "Uh, won't my cavity just get worse in 6 months??" I was in enough pain already though (with beads of sweat to prove it) so I agreed despite my concerns.

    I ended up missing that next appointment.

  • Mapping Google Access Data from (suit)men

    January 18, 2008  |  Mapping

    There's a nice real-time (?) map on (suit)men Entertainment. Click the black rectangle on the bottom left-hand corner to see the entire map. Supposedly the map is powered by Google, so I want to say it's showing search data or something of that sort. To be honest though, I have no clue.

    Whenever a number pops up, there's a line that connects some country to Japan (the site's origin), so I'm guessing they're mapping something like accesses to the (suit)men site from whatever country. Oh well, no matter. Look how pretty. It's entertainment, and it managed to entertain me for a good few minutes (which says alot with my short attention span :). Does anyone know what they're showing?

  • A Primer on Information and Data Visualization

    January 14, 2008  |  Data Art

    On We Make Money Not Art is a summary of Jose-Luis's talk on some of the history of visualizing data and some more modern pieces.

    It begins with Charles Joseph Minard's march of Napoleon and then onto John Snow's cholera map, both of which were made ever so popular by Tufte. By now, if you've cracked open an infovis book, you've seen both.

    Moving on to more modern stuff, there's The Dumpster, 10x10, Listening Post among some other interesting pieces. If you're new to visualization, it's a good "intro to vis" post. If you've been around for a while, you've probably seen most of the examples, but there might be a couple you haven't.

    On a semi-related note, there's also an interview with Miguel on WMMNA discussing our humanflows project. Thanks, Regine!
