The image shows the sample code provided in the text written in Apache Spark and Python. The resulting data set is shown in a graph below the code sample. The graph plots months of a year on the x-axis, and yearly increases from -40% to 40% on the y-axis in 10 percent increments. The trend starts low in the beginning of the year at -30% in January, before increasing over the year until July, and lowers to -30% in December.
