ggplot2 is a popular data visualization package in R that allows users to create visually appealing and customizable plots. Here are some examples of using ggplot2 to create different types of plots:

1. Scatter Plot:
   ```
   library(ggplot2)
   ggplot(data = iris, aes(x = Sepal.Length, y = Sepal.Width)) +
     geom_point()
   ```
   This code creates a scatter plot using the iris dataset, with Sepal.Length on the x-axis and Sepal.Width on the y-axis.

2. Line Plot:
   ```
   ggplot(data = economics, aes(x = date, y = unemploy)) +
     geom_line()
   ```
   This code generates a line plot using the economics dataset, with date on the x-axis and unemploy on the y-axis.

3. Bar Plot:
   ```
   ggplot(data = diamonds, aes(x = cut)) +
     geom_bar()
   ```
   This code produces a bar plot using the diamonds dataset, displaying the frequency of different diamond cut categories on the x-axis.

4. Histogram:
   ```
   ggplot(data = mpg, aes(x = hwy)) +
     geom_histogram()
   ```
   This code creates a histogram using the mpg dataset, representing the distribution of highway miles per gallon values.

5. Box Plot:
   ```
   ggplot(data = iris, aes(x = Species, y = Sepal.Width)) +
     geom_boxplot()
   ```
   This code generates a box plot using the iris dataset, showing the distribution of Sepal.Width across different species.

6. Heatmap:
   ```
   ggplot(data = flights, aes(x = month, y = day, fill = n)) +
     geom_tile()
   ```
   This code produces a heatmap using the flights dataset, displaying the number of flights on different days of the year.

These are just a few examples of the types of plots you can create with ggplot2. The package offers extensive options for customization, including adding labels, titles, legends, adjusting colors, and more. With ggplot2, you can create a wide range of plots to effectively visualize and explore your data.
