d3.js spinnig globe with bars.

This is d3.js analogue of WebGL implementation of globe. Code base was taken from codepen.io. My question on the stackoverflow about how to hide bars gradually is here. Chart usage:

new Globe("/data/cities.csv")

Chart use very simple data format. Actual csv file you can find here. Source code available here. Chart show population of largest cities of the world and some capitals.
