Tools & Data
What data visualisation tools are out there on the web that are easy to use - and free? Here on the Datablog and Datastore we try to do as much as possible using the internet's powerful free options. That may sound a little disingenuous, in that we obviously have access to the Guardian's amazing Graphics and interactive teams for those pieces where we have a little more time - such as this map of public spending (created using Adobe Illustrator) or this Twitter riots interactive. But for our day-to-day work, we often use tools that anyone can - and create graphics that anyone else can too. So, what do we use? Google fusion tables
Review April 20, 2011 06:00 AM ET 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. Want to see all the tools at once? For quick reference, check out our chart listing all the tools profiled here.

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.

Qui dit ouverture des données publiques dit aussi travail en commun, rencontres, réseaux, communautés. Dans cette partie "Forum" de notre site nous vous proposons d'échanger, de questionner, de débattre de vos idées. Concrètes, poétiques, drôles, efficaces, utiles, les idées d'aujourd'hui seront les services de demain... Pas de débats techniques qui trouveront leur place dans l'espace développeur mais bien une place publique de l'imagination ! Pour inventer ensemble les services de demain ...
