df <- data.frame(

  y = runif(20, 10, 15),
  grp = rep(c("A", "B"), each = 2)
)

df$ymin <- df$y - runif(20, 1, 2)
df$ymax <- df$y + runif(20, 1, 2)

g2(df, asp(x = x, color = grp)) %>%
  fig_error(asp(ymin = ymin, ymax = ymax), adjust("dodge")) %>%
  fig_interval(
    asp(y = y),
    adjust("dodge"),
