Now that the globe is finished, it's time to start adding the data. We will use the data format as it is provided by the original inspiration for this recipe: http://code.google.com/p/webgl-globe/.
Data sets come in series of repeating (latitude, longitude, magnitude) tuples. The latitude and longitude map to a place on the globe. The magnitude represents the actual data we want to show, in this case, the population at that location.
We will start from the end result in the previous recipe.The data set can be downloaded from http://code.google.com/p/webgl-globe/source/browse/globe/population909500.json.
Click on the View raw file link to download the actual JSON file. Store that file in the lib folder of the project.
