ggplot2
It is of my interest to use
ggplotpackage to visualize some fun data. In this post, I tried to play with a Nobel Prizes Data including countries, prize year, each prize. The goal is to plot a cumulative traceplot of Liberty Nobel Prizes for top 10 countries.
1 Load Packages
tidyverse package include some very useful tools such as ggplot2, tidyr and dplyr.
ggimage package was used to add country flags to ggplot layer. LaCroixColoR package used for selecting different colors.
2 Data
Import the data.

pull() function is similar to use [] to return the value of one column.
Adding some columns such as the total number of Liberty Prizes (n_prize), the first year of prize, the last year and the cumulative prizes.
