The Evolution of US Girl Names: Bubbled

Sometimes you see something extremely simple looking but you can't figure out how it's done. This video shows, in bubble form, how the popularity of girl's names in the US has changed in the last 135 years. The bigger the bubble, the larger it appears in the box of bubbled names. I'm sure people with experience in After Effects could easily figure out how to make this, but to a person like me, I have a hard time trying to imagine how to create this video. 

I think that whoever designed this graphic did a good job by color-coding the names in alphabetical order. It makes it easy to look for specific names such as your mom's or grandmother's name. It's funny to see names like Gertrude, Bessie, and Agnes in the earlier years and imagine that some attractive people were named Gertrude back in the day.
