  fig_point(
    asp(shape = "circle", size = 3),
    fillOpacity = 0.3, stroke = 0
  ) %>% 
  planes(~cut, type = "rect") %>% 
  motif(padding = c(32, 8, 48, 48))

Recreation of this example.

g2(diamonds, asp(carat, price, color = cut)) %>% 
  fig_point(
    asp(shape = "circle", size = 3),
    fillOpacity = 0.3, stroke = 0
  ) %>% 
  planes(~cut+clarity, type = "rect") %>% 
  motif(padding = c(32, 8, 48, 48))

List

Recreation of this example.

  )

df <- df %>% 
  left_join(total, by = "clarity") %>% 
  mutate(price = (price / total))

df <- data.frame(
  x = rep(1:50, 2),
  y = c(cars$speed, cars$dist),
  grp = rep(c("Speed", "Dist"), each = 50)
)

g2(df, asp(x, y, color = grp)) %>%
