A data analyst is working with the following plot and gets an error caused by a bug. What is the cause of the bug? ggplot(data = penguins) + geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g)) Status: [object Object] 1 point The code uses a plus sign instead of a pipe. The plus should be at the end of the first line. A function name needs to be capitalized. A missing closing parenthesis needs to be added
