Using the penguins data,
Map bill depth to x-axis, bill length to y-axis, species to shape and color.
Add a layer of points and set the size of the points to 4.

ggplot(penguins,
       aes(x = bill_depth_mm,
           y = bill_length_mm,
           shape = species,
           color = species)) +
  geom_point(size = 4)

Using the penguins data,
Map bill depth to x-axis, bill length to y-axis, species to shape.
Add a layer of points and set the size of the points to 4.
Add labels to x-axis (Bill Depth(mm)), y-axis (Bill Length(mm)), and the title of the plot (Palmer Penguins).

ggplot(penguins,
       aes(x = bill_depth_mm,
           y = bill_length_mm,
           shape = species,
           color = species)) +
  geom_point(size = 4) +
  labs(x = "Bill Depth (mm)",
       y = "Bill Length (mm)",
       title = "Palmer Penguins")
