geom_violin

using TidierPlots
using DataFrames
using PalmerPenguins

penguins = dropmissing(DataFrame(PalmerPenguins.load()));

ggplot(penguins, @aes(x = species, y = bill_length_mm)) +
    geom_violin()

Unlike in ggplot2, you cannot put the categorical variable on the y-axis:

# This causes unexpected output
ggplot(penguins) +
    geom_violin(@aes(x = bill_length_mm, y = species))

Instead you can pass orientation = :horizontal as an optional argument:

ggplot(penguins, @aes(x = species, y = bill_length_mm)) +
    geom_violin(orientation = :horizontal)

ggplot(penguins, @aes(x=species, y=bill_length_mm, dodge=sex, color=sex)) +
    geom_violin()
