Inspired by Hans Rosling’s TED Talk: The best stats you’ve ever seen.
The code is taken nearly verbatim from the gganimate example.
install.packages(c("devtools", "dplyr", "ggplot2", "readr"))
library(devtools)
devtools::install_github("dgrtwo/gganimate")
Note that gganimate requires ImageMagick. To install it, use Homebrew on a Mac and Linuxbrew or apt-get or yum on Linux:
brew install imagemagick
sudo apt-get install imagemagick
sudo yum install imagemagick
library(dplyr)
library(gganimate)
