Develop a script in R to create a violin plot displaying distribution of a continuous varible, with separate violins for each group using ggplot2

Step 1:Load the library

library(ggplot2)

Step 2:Load the dataset

data(iris)
head(iris)

  Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1          5.1         3.5          1.4         0.2  setosa
2          4.9         3.0          1.4         0.2  setosa
3          4.7         3.2          1.3         0.2  setosa
4          4.6         3.1          1.5         0.2  setosa
5          5.0         3.6          1.4         0.2  setosa
6          5.4         3.9          1.7         0.4  setosa

Step 3: Create violin plot using ggplot

ggplot(iris, aes(x = Species , y = Sepal.Length , fill = Species))+
  geom_violin(trim = FALSE, alpha=0.6, color= "black")+
    labs(title = "Distributions of petal length by iris Species",
       x = "Species",
       y = "Petal.Length")+
  theme_minimal(base_size = 14)
