Violations of graphical excellence and integrity

Find a data-focused visualization on one of the following websites that is a negative example of the principles that Tufte describes in The Visual Display of Quantitative Information.

Upload the image for the visualization to this directory and display the image inline in this notebook.

# Add your filename and uncomment the following line:
Image(filename='Assignment04b.png')

Describe in detail the ways in which the visualization violates graphical integrity and excellence:

This graph violates integrity by its lack of labeling and detail. I do not know what unit or denomination the y axis follows. The title suggests that the graph represents both oil and food, but there is only one line on the graph. Even if the graph represents both products, I think seperating them would have been better. The spikes and dips in history are not labeled as Tufte suggests, and there is no data variation.
