If you are a computer person then you most likely heard of treemap visualizations to view hard disk usage statistics. One such example that comes to mind is WinDirStat. This article is not about WinDirStat, but is about an online application, called Newsmap, that gathers vast amounts of news articles (from the Google News Aggregator) and presents the news in a treemap visualization format. The power of this is that you can visually take in more information and readily pick out, from the treemap, what news has been given the most coverage. Newsmap has become one of my daily reads and is very easy to learn and use.
Newsmap is an application that visually reflects the constantly changing landscape of the Google News news aggregator.
A treemap visualization algorithm helps display the enormous amount of information gathered by the aggregator. Treemaps are traditionally space-constrained visualizations of information. Newsmap‘s objective takes that goal a step further and provides a tool to divide information into quickly recognizable bands which, when presented together, reveal underlying patterns in news reporting across cultures and within news segments in constant change around the globe.
Newsmap can be customized for your personal use to display news from various countries and can be further personalized to provide news from specific news categories (such as world news, business news, sports, entertainment, health, technology, etc.)
