Delightful and revealing graphics can emerge from swathes of seemingly impenetrable facts and figures. My first encounter with this phenomenon was the work of in books like The Visual Display of Quantitative Information and Envisioning Information. Latterly, has popularised data visualisations, not least the work of David McCandless at .
Beyond the world of publishing and journalism, there is a growing public interest in data and open licensing. The availability of great free software to crunch the numbers—such as and —leads us at Tate to conclude that the time is right to share.
As part of the Archives & Access project, our legal team is working hard to identify content we can release under Ìý±ô¾±³¦±ð²Ô²õ¾±²Ô²µ.
In a parallel piece of work, we have been modernising our web infrastructure to support the new features of the Archives & Access project.

Soon, metadata and imagery from °Õ²¹³Ù±ð’s fascinating archive will further enrich this dialogue.
