library(vchartr)

vchart(countries_gdp) %>%
  v_circlepacking(
    aes(lvl1 = REGION_UN, lvl2 = SUBREGION, lvl3 = ADMIN, value = GDP_MD)
  )


# With root level
vchart(countries_gdp) %>%
  v_circlepacking(
    aes(lvl1 = REGION_UN, lvl2 = SUBREGION, lvl3 = ADMIN, value = GDP_MD),
    use_root = "World"
  )


# Custom colors
vchart(countries_gdp) %>%
  v_circlepacking(
    aes(lvl1 = REGION_UN, lvl2 = SUBREGION, lvl3 = ADMIN, value = GDP_MD)
  ) %>%
  v_scale_color_manual(c(
