Anyone who has stared with unseemly fascination at Charles Minard’s famous graphic charting the near-annihilation of Napoleon’s Grande Arm�e during its ignominious retreat from Moscow is likely to appreciate IBM’s new project, Many Eyes. It’s still early days, but the site provides you with a very simple way of transforming datafiles into “visualizations” that provide an at-a-glance insight into trends and significant outliers. For example, it took me about five minutes to copy and paste CSO data, upload it, and create this basic treemap that underlines the Irish capital’s overweening status. Yes, I’m really that sad.
