Thanks for your submission! Your d3 code is well written and you've completed all the prompts for the submission. I enjoy the creative nature of your visualization, though I would probably suggest to try another form that may more easily highlight the year over year changes in barley yields by site. This form requires the user to do a lot of interaction to be able to find these trends. Something like a slope chart or a grouped bar chart can be very effective here. You've successfully completed the course assignment. Expect a certificate to come into your inbox soon.
