The Yahoo! Mail Visualization [yahoo.com], designed by Periscopic, aims to show of the network processing power required to run a vast emailing service by revealing the streams of keywords that are sent around the globe in real-time.
The geo-located circles on the world map represent the activity and volume of processed emails, totaling to about 5.6 billion emails a day. Current and predicted email traffic is show at the bottom of the screen. A streamgraph shows the top 10 keywords used in email subject lines over the last 5 minutes (at least from those countries that have no strict privacy laws). Both views allow for zooming into specific continents, and for filtering the spam from the non-spam email (which actually occur to a ratio of 1 to 4). Additional infographic illustrations further explain the email filtering processes.
