• Tracking Hurricane Gustav – How Hard is it Going to Hit?

    August 31, 2008  |  Mapping

    Stamen has taken a step towards the concrete with their recent Hurricane Tracker for MSNBC. From what I can tell, it updates every couple of hours or so. The tracker shows where Hurricane Gustav has been and where it's headed and provides information on wind speed, ground speed, and location.

    From the map we see a development from tropical depression in the Caribbean Sea, to a big category 4 over Pinar Del Rio, and then something between a category 3 and 2 as it moves over New Orleans. Gustav dwindles to a tropical storm as it moves towards Dallas. With mandatory evacuations of New Orleans starting yesterday, here's to hoping everyone finds somewhere safe to stay.

  • How Open Should Open Source Data Visualization Be?

    August 29, 2008  |  Visualization

    I used to ride my bike to school, and I always forgot my U-lock. Instead of riding back for it, I'd just stash my bike unlocked in between a cluster of bikes. I told my friend jokingly, "It'll be OK. 98% of people are good." One day I got out of class, and my bike was stolen.

    I was cleaning up some Actionscript in preparation for a tutorial post on how to make your own animated Walmart map, but a couple of bad memories involving stolen code and bad knockoffs (of my work) stopped me midway. I had to think:

    Is releasing my code the best thing to do?

    I'm sure the consensus is a resounding yes, but what's to stop some lazy person from ripping off my code and pawning it off (or worse, selling it) as their own? What if I want to sell my visualizations? I am after all a lowly graduate student. It'd be nice to have another income stream.

    On the other hand, had others before me not released their work under that wonderful BSD license, I would not be able to do what I do. At least not as easily. Modest Maps? Free. TweenFilterLite? Free. Flare Visualization Toolkit? Free. If I don't follow suit, does that make me selfish? Yes, it does.

    Giving Back to the Community

    I've heard that phrase, giving back, so many times in both the real-life sense and the digital one, but it never made much sense to me. I mean, I got it, but I never really got it.

    Perhaps I never understood it, because I wasn't using much of the community's resources nor did I have anything to give back. I have something to give back now. I can help people learn in the same way that others before me have and still do. I'm incredibly thankful to those who maintain these open source projects and still help me out from time to time when there's really nothing in it for them.

    The least I can do is continue to promote this idea of openness and help this small field of data visualization flourish into what it deserves to be. It's why I blog, and it's why I should give back, but to what extent?

    Making the Case for Open Source Data Visualization

    My dilemma brought me back to a Data Evolution post on open source data visualization. It highlighted three things:

    1. Open Tools – As in freely available software tools like R and Processing.
    2. Open Code – How often have you seen a visualization and wondered, "How did they do that? If only the code were available."
    3. Open Data – Oh so important in data visualization. The core. Open data means more people can try out different methods.

    It's not always possible to attain all three. For example, we pay money for software because the companies would not exist otherwise. It's a business, and to think that software companies would develop a bunch of free software is unrealistic. Also, oftentimes, data just can't be shared – usually because of privacy issues. Lastly, open code doesn't make sense a lot of the time. The DE post grades The New York Times with a D for openness, but they're a news business, not a visualization repository.

    While we can't always attain all of three things, there's no reason why we can't try to strive towards that ideal. As someone I know likes to say – strive for perfection. You might not reach that standard, but you could end up with something close.

    Open source is a development method for software that harnesses the power of distributed peer review and transparency of process. The promise of open source is better quality, higher reliability, more flexibility, lower cost, and an end to predatory vendor lock-in.

    Tweeting Thoughts

    I of course tweeted this in the middle of the night while watching the day's remaining olympic events - to release code or not to release code. Here are are some of the replies:

    @rpj: To release, always! (When legally possible.)

    @ehrenc: re: code. You could always release half the code :)

    @pims to release code. There's some brilliant people around that can build on top of what you did. Open world :)

    As for me, well, let's just say you should expect to see tutorials – complete with code – in the coming weeks.

  • Look at My Neato Lollipop Chart – Widgenie

    August 27, 2008  |  Ugly Charts

    As some commented on an earlier post, FusionCharts provides an easy way for people to hack together statistical graphics - sometimes not so attractively - and put the results on their websites. Widgenie serves as case in point. The concept of the application is all well and good. Upload some data and embed the "interactive" graphic on your blog, website, etc.

    The realization of that idea however, needs some work. Aside from my difficulties logging on, changing my password, and non-flexible data upload, the widgets are, for the most part, just FusionCharts out of the box. Like the lollipop I made (below)?

  • Plummeting Infographics from I.O.U.S.A – A Nation in Debt

    August 26, 2008  |  Infographics

    I haven't seen I.O.U.S.A. yet, but from the online bonus clips, it looks like it could be a good watch for you infographics junkies. The documentary examines the growing national debt and the consequences it will have on its citizens, so the source material sort of lends itself to plummeting time series charts with dramatic flare.

    Here's one showing personal savings rate over time:

    Deficits and social security over time:

    Debt-to-GDP projections:

    A $53 Trillion Federal Financial Hole:

    Those are just the bonus clips. I'm sure there are plenty more in the actual documentary.

  • History’s Greatest Journeys – Wanderlust from GOOD

    August 25, 2008  |  Mapping

    GOOD Magazine, in collaboration with Graham Roberts, maps the most famous journeys in history - some fiction, some non-fiction. Wanderlust includes trips like Around the World in 80 Days and Journey to the Center of the Earth to the voyages of Marco Polo and Charles Lindbergh's transatlantic flight. However, it's not just a map with journey lines on it; Wanderlust is a history lesson. Select a trip for a summary and explore highlights of the journey.

  • Amusing Disney Org Chart – From Walt on Down

    August 22, 2008  |  Infographics

    I'm not sure how old this Disney org chart is, but I'm guessing very. Ink and paint? What are those? In any case, it's amusing. Why are nurse, army coordinator, police, and morgue on there? The animation business is clearly more complex than I thought.

  • Physical Graphs as Critique on American Culture

    August 20, 2008  |  Data Art

    These wooden graphs by Joshua Callaghan show uh, something on the left and military spending on the right. While I wouldn't call them any type of spectacular representation of data, I do like the idea of placing data into a physical space. We always get our graphs on a computer screen or on paper at best, which can take the human out of the data. It's easy to forget that a single data point can represent an entire human life (or death). Keep that in mind the next time you analyze a dataset.

  • 3 Worthwhile Alternatives to the Pie Chart

    August 19, 2008  |  Statistical Visualization

    A while back I asked what you wanted to see more of on FlowingData. Thanks to the 447 of you who responded.

    I was actually kind of surprised that there were so many votes for statistical visualization. I thought there would be more of a balance between design, art viz, and stat viz. I was, however, happy to see that the second most voted-on choice was "All of the Above." I must be doing something right! So by popular demand, here's some statistical visualization.

    Pie Chart Alternatives

    Since the above pie chart is making some of you cringe in agony (although I can't imagine why), let's take a look a few alternatives for the pie chart using the same poll results.

    Bar Chart

    How about a horizontal bar chart? The results are sorted and you can easily see the difference in voting counts.

    Stacked Bar Chart

    The above bar chart is missing a little something though. It doesn't explicitly show that each bar is really a part of a whole - in this case, all the people who voted. How about a stacked bar chart then? It shows the groupings and is a little easier to read than the pie chart in the sense that it's linear differences as opposed to radial.

    Bubble Chart

    Let's not forget our friends the bubbles. Carrying the same "problems" as a pie chart, the bubbles on the left are essentially a table with some flavor.


    Personally, I still like the pie. Which one do you think is best? Or is there something else that might have been better than the above? How about a mosaic plot? Donut graph? A plain table?

  • Tell Stories With Interactive Timelines from Dipity

    August 18, 2008  |  Online Applications, Visualization

    Timelines, much like calendars, can be used to show changes over time in a straightforward way. When you have a bunch of events that occurred at certain times, mark them on a timeline, and you quickly get a sense of what's going on. Take the timeline of 10 largest data breaches for example. You see breaches get more dense as time goes by.

    Wrap this idea into web application form, and you get Dippity. There have been similar timeline applications, but Dippity does it a bit better with a primary focus on telling stories with timelines and a good interface. Zoom in, zoom out, drag, and get alternative views as flipbook, list, and map.

    Below is a little bit of context to my gas price chart. Check out the full version for a better idea of what Dippity offers. Continue Reading

  • Is There a Market for Premium Online Data Visualization?

    August 15, 2008  |  Visualization

    Ever since I posted my visualization that shows the spread of Walmart, I've gotten a lot of emails asking how I did it, if I've considered applying it to other datasets, or if I could help with a customized version of the Walmart visualization. I've gotten similar inquiries about the gas price graphic. This makes me wonder -- is there a market for premium visualization online?

    Existing Premium Visualization

    I know there's definitely a market for data-specific visualization - viz made specifically for a certain type of data - otherwise design groups like Bestiario and Stamen wouldn't be around. But what about visualization that developers (or non-developers) can integrate into websites and applications with their own data?

    FusionCharts

    For example, FusionCharts lets developers integrate the more traditional visualizations like bar charts and basic maps into their websites. Everything runs in Flash and has a little bit of animation and some interaction. According to the site's homepage, 30,000+ developers use FusionCharts. Licenses run from $69 for individuals to $1,999 for enterprise.

    Constellation Roamer

    Daniel develops Constellation Roamer. It's a network graph interface that lets you explore connectedness. The Roamer has been out for about four months now and according to Daniel, has sold about 10 individual licenses at $550 each. This is interesting because the leads come from search engines without any advertising or publicity. While the sales are modest, he's also gotten a lot of freelance work for customized versions of the Roamer to keep him plenty busy.

    Relation Browser

    Similarly, Moritz developed Relation Browser a couple years ago and says he gets an inquiry about once a week even though, like Daniel, doesn't advertise. Relation Browser is a network graph visualization that lets you explore relationships. The example below shows relationships between countries, but can also be applied to something like a social network. Moritz releases his code for free, but requires commercial vendors to purchase a license for 400 Euros (about $600) each.

    Free Visualization Tools

    So there's definitely some kind of demand for a more refined online visualization; however, there's been a growing number of free visualization tools available to developers. Do these take away the need for paid online visualization tools?

    Google Visualization API

    Most well known is perhaps Google's visualization API that they released in March, including the motion chart shown below. The API also includes a basic graphing utility along with a hodge podge of some other, uh, not so useful tools.

    Many Eyes

    Many Eyes promotes social data analysis and is best known for its interactive visualizations. Last year, they brought embeddable visualization, mostly for bloggers to share with others. However, the drawback is that you can't push frequently-updated data into the Many Eyes application. The only way to get an updated visualization is to edit an existing dataset or upload a new one manually.

    Room for Both Free and Premium

    It seems that there's room for both. While the free tools from Google and Many Eyes are useful in their own right, premium visualization can provide a higher level of customization (for complex data streams and aesthetics) and integration into a site or an application.

    Tweeting Thoughts

    I asked the same question on Twitter a few days ago and got some interesting responses from my Twitter friends:

    @Omomyid: hmmmmm, how would you make it extensible though? The thing about cool infographics is that they are purpose built right?

    @chris23: prolly a possible analyst service to provide visualizations/tools for market interests.

    @der_mo: yes, totally. I keep selling the relation browser (http://der-mo.net/relationB...) although it is a couple of years old...

    @hungryclone: maybe to companies w/ no dedicated employees that know how to make them?

    Your Thoughts

    What do you think? Is there a marketplace for visualization on the web or do the free APIs make it a moot point?

  • Many Eyes Adds Wordle to its Extensive Visualization Toolbox

    August 13, 2008  |  Data Art, Online Applications

    I'm sure you've seen Wordle by now, which puts an artistic spin on the traditional tag cloud. An application by Jonathan Feinberg, Wordle lets you put any text or RSS/atom feed in as input and get a cloud of words sized by frequency and arranged every which way. Above is a Wordle cloud of the current FlowingData feed.

    Many Eyes recently added Feinberg's visualization to their slew of other visualization tools.

    Wordle marks a departure from the more analytical visualizations on Many Eyes. Why bring a self-described “toy” to a site for social data analysis? People have reported finding value beyond entertainment in creating these word clouds. Teachers have used Wordles in classrooms as conversation catalysts; others have created them to express their identities, and scholars have used them to visualize the output of statistical explorations of texts.

    No doubt Many Eyes, with Martin Wattenberg and Fernanda Viégas (who know a thing or two about design) at the helm, recognizes that data visualization isn't always about analytics and exactness. Sometimes visualization is just about getting people to think.

  • I’ll Take My Infographic in Bright Orange, Men’s Medium

    August 12, 2008  |  Infographics

    The Shirt Project, by Rich Watts and Louise Ma, takes the infographics out of the newspaper and puts them onto brightly colored tshirts. What a great idea. They put out a new shirt every couple of months and topics range from the New York steam explosion to a bit of pop culture celebrating the birthdays of Michael Jackson, Prince, and Madonna. Subscribe to tshirts the same way you subscribe to newspapers. For the low price of $20, you can be both stylish and educational.

  • Britain From Above – Beautiful Use of Satellite Technology

    August 11, 2008  |  Mapping

    The BBC has a gorgeous documentary series that started yesterday -- Britain from Above. They take a look at Britain from the skies using satellite technology and GPS data. Watch patterns emerge as taxis, ships, and planes travel back and forth and information and data pass through Britain's national telephone network. The imagery is beautiful. I love visualization that brings data to life.

    The high-resolution videos don't seem to be working right now, but here's just a small sample:

  • Watch the Rise of Gasoline Retail Prices, 1993 – 2008

    August 8, 2008  |  Projects, Statistical Visualization

    Gas prices have been pretty crazy lately. I'm not used to paying over $45 for a tank of gas in my fuel-efficient Honda Civic. I mean, come on, what the heck?

    So naturally, we want to know, "What do the data look like for gasoline prices?" The Energy Information Administration has this data available for download. They have historic gas prices for certain states (not all, unfortunately) as well as for U.S. regions. Check out the animation showing the rise and fall... and rise.. and fall and rise of U.S. gas prices from 1993 up until now. Things started going crazy in 2006.

  • It’s Like Google Maps with Sim City 2000 – OnionMap

    August 7, 2008  |  Mapping

    Remember SimCity 2000? That was a great game. That was probably the last computer game I played for any significant length of time, and if my Macbook Pro were able to read 5-inch floppies, I'd totally pop it in and build myself a city called Yau Town.

    Put the look of SimCity 2000 together with Google Maps, and you get OnionMap. Most of the site is in Korean, but from what I gather it aims to be something of a tourist guide with a little bit of social network mixed in. That part of OnionMap is a little fuzzy, but it was worth the five minutes for the maps.

  • Map of Olympic Medals in Bubble + Geographic Form

    August 6, 2008  |  Infographics

    Lee Byron, Amanda Cox and Matthew Ericson of the New York Times graphics department map Olympic medals starting from the first one hosted by the International Olympic Committee in 1896 up to the most recent one in Athens. It looks like someone has an affinity for the colliding ball effect. Not that that's bad or anything.

    The Encodings

    Bubbles for each country are arranged geographically (or by rank) and sized by the number of medals that country won. Each continent has its own color. Shift the timeline to look at a different year, and click on a bubble to get a medal breakdown. The one thing that's mysteriously missing is a play button to watch the map morph over time. I'm sure there's a good reason why, but it seems like a natural next step. Although, I guess I can just hold down the arrow keys.

    In any case, good stuff.

    Is it just me, or is anyone else seeing home court advantage playing a role in medal count?

  • Visualize Genomes and Genomic Data – Circos

    August 5, 2008  |  Network Visualization

    Circos is a project by Martin Krzywinski that lets you upload genomic data and visualize it as a network like the one above.

    It is easy to plot, format and layer your data with Circos. A large variety of plot and feature parameters are customizable, helping you make the image that best communicates your data. You supply your data to Circos as flat files (e.g. GFF format), tell Circos what you want plotted using the configuration file, and then create the image.

    While Circos is developed in the interest of visualizing genomic data, it is general enough that you can use it with other types of data that show relationships. The New York Times debate graphic is the first thing that comes to mind. Anyone want to give Circos a spin? Post a link to your image in the comments.

  • New Version of Flare Visualization Toolkit Released

    July 31, 2008  |  Software, Visualization

    A new version of Flare, the data visualization toolkit for Actionscript (which means it runs in Flash), was just released yesterday with a number of major improvements from the previous version. The toolkit was created and is maintained by the UC Berkeley Visualization Lab and was one of the first bits of Actionscript that I got my hands on. The effort-to-output ratio was pretty satisfying, so if you want to learn Acitonscript for data visualization, check out Flare. The tutorial is a good place to start.

    Here are some sample applications created with Flare:
