Google have recently launched a visualization search tool called Search Globe. This tool maps search queries volume on a 3D image of the earth by language for one day.
3D visualization of searches with Search Globe
In a blog post, Valdean Klump of Google’s Data Team explained that the Search Globe visualizes searches from one day, and shows the language of the majority of queries in an area in different colors. He went on to explain that users would see a bright landscape of queries across Europe, and parts of Asia but may see fewer searches from parts of the world that lack Internet access or even electricity like Africa.
