For my final data visualization project, I chose to work with a dataset that showed the prevalence of different religions by country from 1945 to 2010.

I decided to work with this dataset because I was interested in how the demographics of different countries changed over time.

In my visualization, each country is represented by a dot. If more than half of the country practices one religion, the color of the dot is the color that corresponds with that religion. If no one religion is overwhelmingly common, the dot is black. If you hover over a dot, a pie chart will appear of all the religions in that country.

If you press L, the date goes up by 5 years. You can go back by pressing E.

One interesting thing I noticed during this project is that the US started getting more diverse by the end, which makes sense. Also, a lot more people started being nonreligious.

Something I still wonder about is what this would have looked like in a broader timeline. It would be interesting to see how imperialism would affect the pie charts.

The most challenging moment of this project was figuring out how to draw the pie charts.

If I had more time, I would like to make it so that individual states had dots (specifically for the US: it would be interesting to see the difference between certain states' demographics).

My proudest moment during this project was when I managed to color code the dots. The map was starting to look a lot more professional and finished!
