Hans Rosling’s Gapminder using wbstats

library(tidyverse)
library(wbstats)

my_indicators <- c(
  life_exp = "SP.DYN.LE00.IN", 
  gdp_capita ="NY.GDP.PCAP.CD", 
  pop = "SP.POP.TOTL"
  )

d <- wb_data(my_indicators, start_date = 2016)

d %>%
  left_join(wb_countries(), "iso3c") %>%
  ggplot() +
  geom_point(
    aes(
      x = gdp_capita, 
      y = life_exp, 
      size = pop, 
      color = region
      )
    ) +
  scale_x_continuous(
    labels = scales::dollar_format(),
    breaks = scales::log_breaks(n = 10)
    ) +
  coord_trans(x = 'log10') +
  scale_size_continuous(
    labels = scales::number_format(scale = 1/1e6, suffix = "m"),
    breaks = seq(1e8,1e9, 2e8),
    range = c(1,20)
    ) +
  theme_minimal() +
  labs(
    title = "An Example of Hans Rosling's Gapminder using wbstats",
    x = "GDP per Capita (log scale)",
    y = "Life Expectancy at Birth",

Using ggplot2 to map wbstats data

library(rnaturalearth)
library(tidyverse)
library(wbstats)

ind <- "SL.EMP.SELF.ZS"
indicator_info <- filter(wb_cachelist$indicators, indicator_id == ind)

ne_countries(returnclass = "sf") %>%
  left_join(
    wb_data(
      c(self_employed = ind), 
         mrnev = 1
          ),
    c("iso_a3" = "iso3c")
  ) %>%
  filter(iso_a3 != "ATA") %>% # remove Antarctica
  ggplot(aes(fill = self_employed)) +
  geom_sf() +
  scale_fill_viridis_c(labels = scales::percent_format(scale = 1)) +
  theme(legend.position="bottom") +
  labs(
    title = indicator_info$indicator,
    fill = NULL,
    caption = paste("Source:", indicator_info$source_org) 
  )
