A bar chart showing population of World religions in 2010. Data shown is from the Pew-Templeton Global Religious Futures Project.
This data is taken exactly as-is from the Pew-Templeton Web site, including labels for religions, and does not represent my opinions. This data may not be 100% accurate, I’m not sure. I’d be curious to see results from others sources that show a similar comparison of World religions.
The code for this chart is derived from example 105 of the screencast Introduction to D3.js. Also, the tool tip approach draws from d3noob’s Simple d3.js tooltips block
