• How to: make a scatterplot with a smooth fitted line

    Posted to Tutorials  |  Tags: ,

    Maybe you have observations over time or it might be two variables that are possibly related. In either case, a scatter plot just might not be enough to see something useful. A fitted line can let you see a trend or relationship more easily.

    As an example, we'll take a look at monthly unemployment data, from 1948 to February this year, according to the Bureau of Labor Statistics.

  • Data Underload #15 – Life Simile

    You never know what you gonna get. Life is also known to be like: a box of crayons, a park, a taxi, the surf, falling in love, a bowl of cherries, or a slideshow.

  • The periodic table to end all periodic table ridiculousness

    Posted to Miscellaneous  |  Tags:

    A few centuries ago, scientists designed the periodic table to organize the elements we knew about in a way that was useful. Elements were grouped by similar properties on the horizontal and vertical. Somewhere down the line, more recently, someone decided to squeeze a different dataset into the same structure. It made very little sense, but it caught on. Maybe because it looked scientific and official. I don't know.

    Now there's a periodic table of funk, typefaces, candy, and heck, there's even one for visualization.

    So many tables. How do we sort all of them? With another periodic table, of course, and so without further ado, here is the periodic table of periodic tables by Bill Keaggy. Yay?

  • IBM data propaganda – babies and old guys with glasses

    Posted to Statistics

    IBM has been spreading the whole "smarter planet" spiel for a while now, but in the past few days, they've revealed the punchline. It's data. The key to a smarter planet is learning how to process and extract information from the 15 petabytes of data we generate per day.

    Surprising? No, not at all. Data's the hot thing right now, and that's where the money's at. Learn how to process all of it and you're gold.

  • The Growing Plague that is Spam

    Spam sucks. We all hate it, but no matter how good the filter, something always seems to get through. Want some cheap Vi4gr4? I can tell you where to get it. New Scientist takes a look at the spamdemic. It costs very little to send tens of thousands of emails, but it only takes a tiny percentage of idiots to make it all worth it for spammers.

    Seriously - who falls for these things?

  • Poll: What do you mostly use visualization for?

    Posted to Polls, Visualization

    We use visualization for a lot of different things, and its purpose varies person-to-person. Some use it to report the news. Others use it purely for analysis and decision-making. Some even use it for artistic expression. What do you use visualization for? Select the answer that best fits you below. If you select "other," let us know what that means in the comments.

  • Buy and sell data at Data Marketplace

    Posted to Data Sources

    Add another site to the list of places to find the data you need. Data Marketplace connects people who want data to people who can find, scrape, and cull data.

    Here's how it works. If you want data, you put in a request and optionally, a deadline and budget. A provider can then go find that data for you, maybe through scraping a difficult-to-parse website, and then post it online. You then have the option to purchase the tabular data.

    There are three big humps to get over though for Data Marketplace to work.

  • Graphical perception – learn the fundamentals first

    Posted to Design  |  Tags:

    When it comes to visualization, especially on the Web, you have to be open-minded, and you should be willing to try new things. There’s no advancing otherwise. However, before you dive into the advanced stuff - like just about everything in your life - you have to learn the fundamentals before you know when you can break the rules.

    You have to know what flavors work together and against each other before you cook a feast fit for a king. You have to learn grammar and spelling before you can write a book that others will actually enjoy.

    So when you’re learning to visualize data, do yourself a favor and learn the basic rules first. Then you can spend the rest of your days breaking them.

    We’re inventors - we’re creators. And that’s the most important thing about what we do. And I think we should welcome failure every once in a while.

    Hannah Fairfield - NYT Graphics Editor, Malofiej 18, March 2010

    Last year at Malofiej, one of the major awards ceremonies for infographics in journalism, The New York Times took home 'Best in Show' for their work on box office receipts from 1986 to 2008. I'm sure most of you saw it. It was non-traditional. It was an adaptation of Lee Byron's streamgraph, which he had previously applied to last.fm music listening habits - a smoothed stacked area chart at the core.

  • Notes from Interactive Infographics #interinfo #sxsw

    Posted to Infographics, News

    Yesterday was the Interactive Infographics panel at South by Southwest, and if Twitter is any indication of how it went, I'd say the panel had a captivated audience. I wouldn't expect anything less from the four panelists, Ben Fry (Processing), Shan Carter (NYT), Casey Caplowe (Good), and Eric Rodenbeck (Stamen)

    Unfortunately, I didn't get to attend, but luckily I was able to follow the play-by-play on Livefyre (sort of a cross between chat and forum) along with some excellent notes from @jpmarcum and @bryanconnor. Here are the important bits I was able to glean.

    The bulk of the time was spent showcasing the work from the four groups. I think you can find most of the projects through FlowingData. Just use the search form on the bottom right of this page. The good stuff came towards the end during the Q&A.
