Imagine an actual physical 6-foot-diameter globe floating before your very eyes, displaying every imaginable dataset about our planet. Created by the United States National Oceanic and Atmospheric Administration (NOAA), the Science On a Sphere® (SOS) “is a room sized, global display system that uses computers and video projectors to display planetary data onto a six […]
Kalev's latest Foreign Policy columns explores global protest activity over the last 35 years, finding that the Arab Spring touched off an increase of 25% in global protest activity, but that current levels are still significantly below 1980 levels. A case study of Ukraine is provided to show the ability of GDELT's protest data to […]

With today being the 20th anniversary of the genocide in Rwanda, we've received a number of requests for visualizations and insights that show what “big data” analysis of the news media can tell us about the conflict. Similar to the visualization of Nigeria in 2014, we’ve created a TimeMapper visualization, courtesy of the GDELT Analysis […]
Megacities will play an outsized role in global politics and national stability over the coming decades with some estimates suggesting nearly three quarters of the world’s inhabitants will be living in such urban environments by 2050. From water access to sanitation, flooding to healthcare, communications to transportation, megacities present a host of unique challenges, including […]
Perhaps one of the GDELT Analysis Service’s most eagerly-awaited new visualizations is its Global Knowledge Graph Network Visualizer, which allows you to rapidly construct network visualizations of the people, organizations, locations, and themes undergirding global society. Delivered to your inbox is an interactive browser-based network visualization, a spreadsheet of “centrality” and “influencer” rankings, and even […]
Perhaps the most famous visualizations from Culturomics 2.0 were the geographic networks that illustrated how the geography of the world is interconnected through the eyes of the news media. Geographically-situated networks, in which nodes are placed in space at their actual geographic locations, offer an incredibly rich new analytic framework that blends spatial and non-spatial […]
One of the first requests from early previews of the Timeline Visualization tool was the ability to plot countries and themes in a similar way, to make it possible to observe temporal correlations. Countries often exhibit complex temporal interplays in which events or views in one country spill over into neighboring or culturally proximate countries. […]
Emotion has become an increasingly powerful lens through which to explore the world, as a growing literature demonstrates the ability to extract powerful latent cues from our daily discourse and the connection of those cues to physical action. For example, few countries have collapsed in the midst of skyrocketing popular support for their leadership or […]
The concept of time is at once one of the most basic dimensions through which to understand and visualize conflict, yet simultaneously it is one of the more difficult to represent concisely at high resolution. Representing daily change over 35 years requires arraying more than 12,700 data points in a single one-dimensional linear display. Traditionally […]
