purrr and scatterplots
Since ggplot() does not accept lists as an input, it can be paired up with purrr to go from a list to a data frame to a ggplot() graph in just a few lines of code.
You will continue to work with the gh_users data for this exercise. You will use a map_*() function to pull out a few of the named elements and transform them into the correct datatype. Then create a scatterplot that compares the user's number of followers to the user's number of public repositories.

Foundations of Functional Programming with purrr
Anleitung zur Übung
map()overgh_users, use themap_*()function that creates a data frame, with four columns, named"login","name","followers"and"public_repos".- Pipe that data frame into a scatterplot, where the
xaxis isfollowersandyispublic_repos.
