Newsmap is a news aggregation tool that organises news stories, by popularity and volume of reporting, in a visually pleasing treemap—making it extremely simple to see what's going on and how much coverage it's receiving.
At Newsmap you can display news by category (such as World, National, Business, Technology, Sports, Entertainment, and Health) as well as by country (such as US, UK, Spain, Mexico, France and more). You can combine countries and categories to interesting effect, like selecting only technology news across several countries to see a weighted map of what news stories are popular in each country.
Mousing over a story provides a small pop-up summary and image; clicking on any square in the treemap directs you to the story. You can use the site without registration but registering offers customisation and article tracking features such as hiding read articles, toggling previews, adding and removing countries, tweaking the colours and font, and setting what your home view will be. Newsmap is a free service.
