# We use geom_point() to make a scatterplot.

  mapping = aes(
    x = bill_length_mm,
    y = bill_depth_mm

) +
  geom_point()

Claus Wilke talks about scatterplots in Chapter 12 of his book Fundamentals of Data Visualization. Michael Toth also has a long blog post about all of the ins and outs of making scatterplots in ggplot.

You can also find examples of code to make scatterplots on the Data to Viz website , the R Graph Gallery website , and in Chapter 5 of the R Graphics Cookbook.

In the Your Turn solution, I noticed that the way each line break/indentation is different than the way it was presented in the video (which seems to be the default indentation when you hit the enter key/line break). Is there a reason the solution is different? Is one preferable over the other? How do we get the line breaks/indentations in the solution?

Hi Lilly! We'll talk a bit about it in the live session today. It has to do with automatic styling with Air (in this case). Not having line breaks does not make your code wrong. Indentation is important only in specific cases (we'll talk about them in the Quarto lessons). Overall we like line breaks and indentation because it makes it easier to read!
