Visualizing geographic data with the WebGL Globe

The WebGL Globe, introduced by Doug Fritz from the Google Data Arts Team, is an open platform for visualizing geographic data in browsers supporting WebGL, such as Google Chrome. This innovative tool allows users to explore data like world population and Google search traffic through 3D visualizations, utilizing the Three.js JavaScript library to efficiently render thousands of data spikes. These spikes, represented as cubes, are optimized by removing their bottom faces and merging them into a single geometry for smooth performance. The project also tackles the challenge of animating the globe by leveraging the user's GPU for 3D computations and employing vertex and fragment shaders to enhance visuals, such as simulating atmosphere and illumination. Developers are encouraged to create and share their own data visualizations using this platform, with resources available in JSON format, and the hope that a community of creative globes will emerge and be shared.
