The WebGL Globe is an open platform for geographic data visualization. It was created by the Google Data Arts Team and is still in early development. Users are encouraged to copy the code, add their own data, and create their own globes. The user generated visualizations can then be featured on the project’s website. The WebGL Globe is able to display a JSON file. It requires latitude, longitude and the magnitude related with the location. It would certainly be interesting to visualize education related data with open data from the Worldbank, OECD and others.
The primary challenge of this project was figuring out how to draw several thousand 3D data spikes as quickly and smoothly as possible. For each data point, we generate a cube with five faces – the bottom face, which touches the globe, is removed to improve performance. (Google Code Blog)
