Examples


library(vchartr)

# Create a sunburst and auto hide labels
vchart(countries_gdp) %>%
  v_sunburst(
    aes(lvl1 = REGION_UN, lvl2 = SUBREGION, lvl3 = ADMIN, value = GDP_MD),
    gap = 10,
    labelAutoVisible = list(
      enable = TRUE
    ),
    labelLayout = list(
      align = "center",
      rotate = "radial"
    )
  )
# Custom tooltip vchart(countries_gdp) %>% v_sunburst( aes(lvl1 = REGION_UN, lvl2 = SUBREGION, lvl3 = ADMIN, value = GDP_MD) ) %>% v_specs_tooltip( mark = list( title = list( value = JS("val => val?.datum?.map(data => data.name).join(' / ')") ) ) )
# Custom layout options vchart(countries_gdp) %>% v_sunburst( aes(lvl1 = REGION_UN, lvl2 = SUBREGION, lvl3 = ADMIN, value = GDP_MD), gap = 0, innerRadius = c(0, 0.4, 0.8), outerRadius = c(0.3, 0.7, 0.85), labelAutoVisible = list( enable = TRUE, circumference = 1 ), labelLayout = list( list( align = "center", rotate = "tangential", offset = 0 ), NULL, list( align = "start", rotate = "radial", offset = 15 ) ) ) %>% v_specs(padding = 70)
