9.Create multiple histograms using ggplot2::facet_wrap() to visualize how a variable (e.g.,Sepal.Length ) is distributed across different groups in a built-in R dataset.

step 1:Load necessary libraries

library(ggplot2)

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

step2: Create histograms using facet_wrap for grouped data

ggplot(iris,aes(x=Sepal.Length))+
  geom_histogram(binwidth =0.3,fill ="skyblue",color="black")+
  facet_wrap(~Species)+
  labs(title ="distribution",
       x="sepal length",
       y="frequency")+
  theme_minimal()
