“You have brains in your head. You have feet in your shoes. You can steer yourself in any direction you choose. You're on your own, and you know what you know. And you are the guy who'll decide where to go.” Alyson Hurt @alykatData visualisation DIY: our top tools | News | guardian.co.uk

22 free tools for data visualization and analysis - Computerworld
Computerworld - You may not think you've got much in common with an investigative journalist or an academic medical researcher. But if you're trying to extract useful information from an ever-increasing inflow of data, you'll likely find visualization useful -- whether it's to show patterns or trends with graphics instead of mountains of text, or to try to explain complex issues to a nontechnical audience. There are many tools around to help turn data into graphics, but they can carry hefty price tags. The cost can make sense for professionals whose primary job is to find meaning in mountains of information, but you might not be able to justify such an expense if you or your users only need a graphics application from time to time, or if your budget for new tools is somewhat limited.
d3.js
D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. As a trivial example, you can use D3 to generate a basic HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction. D3 is not a traditional visualization framework.
Data.gov
Are you a teacher, professor, or student? Young people across America are learning about Data.gov and we want you to be part of getting data into the classroom. As the Web of linked documents evolves to include the Web of linked data, we’re working to maximize the potential of Semantic Web technologies to realize the promise of Linked Open Government Data. We and our collaborators at the Tetherless World Constellation at the Rensselaer Polytechnic Institute are helping to lead the way in this exciting area! Are you interested in sharing your mashups, apps, and ideas? Do you want to learn how to create app and mashups with some of the data hosted here on Data.gov?
This website contains the on-line versions of books previously published in hard copy by the Federal Research Division of the Library of Congress as part of the Country Studies/Area Handbook Series sponsored by the U.S. Department of the Army between 1986 and 1998. Each study offers a comprehensive description and analysis of the country or region's historical setting, geography, society, economy, political system, and foreign policy.

The following post is from Friedrich Lindenberg , who is a developer at the Open Knowledge Foundation working on CKAN , PublicData.eu and Open Spending . Recently, there has hardly been a week in which there hasn’t been an announcement of a new local, regional or national open data initiative – including ever more extensive catalogues of data that is being opened up ( CKAN alone now runs in 20 or more places). While this is great news for those of us interested in re-using the data, it also means it becomes increasingly hard to keep a good overview of what kind of data are available for which places.

SNAP: Network datasets: 476 million Twitter tweets
Dataset information 467 million Twitter posts from 20 million users covering a 7 month period from June 1 2009 to December 31 2009. We estimate this is about 20-30% of all public tweets published on Twitter during the particular time frame.
Times Developer Network - Welcome
We've just released the Event Listings API, which powers the NYTimes Arts & Entertainment Guide , provides information and details on noteworthy events in and around New York City. For more details, read the blog post .Driving awareness of the Flickr API, projects that use it and those incredible ideas that programmatically exposed systems produce. Think Google API + Amazon API + Flickr API with a bit of GMail thrown in. The developers of Flickr rightly pointed out they want to keep technical discussions directly related to the API on the mailing list. If you have photos or screenshots that illustrate your use of the API, then feel free to add them. Please be selective though - people don't necessarily want to see a dozen almost identical screenshots of your app - just one or two that show off the most interesting aspects.
