Exercise

Animating the private space race

In recent years the major players in spaceflight have shifted from government agencies to private companies. In this exercise, your task is to create an animation to explore the evolution of this "new" space race. The data set private_launches contains the variables:

tag - launch ID
year - launch year
agency_code - agency abbreviation
agency_name - agency name
agency_type - an established private company or a startup
category - success (O) or failure (F) of the launch

plotly, dplyr, tidyr, and purrr have been loaded for you.
