Hatena user id:kaiseh introduces a news mapping mashup service they created [ja] called “Newsgraphy“, based on an earlier mapping service for Hatena blogs released in June (with much fanfare [ja]) called HatenarMaps (also by id:kaiseh). The new service creates a 2-dimensional visualization of news stories from Yahoo News using Voronoi Treemaps, allowing the user to highlight news regions on the map by subject, by date, as well as by person/place/organization.
