Making the blog rounds is Newsmap, a tool for visualizing what’s getting press around the world.
It’s based on a visualization style known as treemaps. I addressed this topic in an interview I conducted with Marti Hearst, where we called out Smartmoney.com’s “Map of the Market” as an example of a useful, usable, and engaging visualization.
Newsmap is quite keen, though Map of the Market, with it’s green-to-red coding signifying economic trends, packs more of a visceral wallop. Perhaps it would be interesting for Newsmap to not just demonstrate popularity whether a meme is gaining ground or falling. Of course, with news, we’d probably expect most items to lose ground, but it would be keen to see those few things that percolate into the mediasphere.
