Step 1:Load the required 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:Plot the box plot

ggplot(iris, aes(x = Species, y = Sepal.Length)) +
  geom_boxplot(
    notch = TRUE,
    notchwidth = 0.6,
    staplewidth = 0.4,
    fill = "red",
    color = "skyblue"
  ) +
  labs(
    title = "Box Plot for Iris",
    x = "Species",
    y = "Sepal Length"
  ) +
  theme_minimal()
