Exercise instructions

Load the ggplot2 package.
Filter the votes_joined dataset for only votes by the United States relating to colonialism, then summarize() the percentage of votes that are "yes" within each year. Name the resulting column percent_yes and save the entire data frame as US_co_by_year.
Add a geom_line() layer to your ggplot() call to create a line graph of the percentage of "yes" votes on colonialism (percent_yes) cast by the US over time.
