Data visualisation DIY: our top tools | News

The Wikileaks war logs: every death recorded. Get Bigger version 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.

Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction. d3.js
Open Knowledge Foundation Blog » Blog Archive » Open Data Search: finding useful datasets, worldwide The following post is from Friedrich Lindenberg, who is a developer at the Open Knowledge Foundation working on CKAN, 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.
