nation=read.csv("nations.csv")

nationgdp=nation|>
  mutate(gdptotal=(gdp_percap*population)/1000000000000)

nationgdpfilter=nationgdp|>
  filter(country=="Colombia"|country=="Chile"|country=="Brazil"|country=="Bolivia")

ggplot(nationgdpfilter,aes(x=year, y=gdptotal,color=country))+
  geom_point()+
  geom_line()+
  scale_color_brewer(palette="Set1")

groupednation=nationgdp|>
  group_by(region,year)|>
  summarize(GDP = sum(gdptotal, na.rm =
TRUE))

`summarise()` has grouped output by 'region'. You can override using the
`.groups` argument.

ggplot(groupednation,aes(x=year,y=GDP,fill=region))+
  geom_area(color="white")+
  scale_fill_brewer(palette="Set2")
