This is a chart made in D3 as a midterm assignment for my Information Visualization class (INFO 441) at the University of Washington.
The assignment was to imitate this chart in D3, which was originally built with Tableau: https://public.tableau.com/profile/david.newman#!/vizhome/shared/NSJ8WB8H7
View the replicated version I built using D3 here: https://kylewistrand.github.io/d3Viz2/
I acquired the data by downloading the Tableau file and saving the CSV file that was used in this viz separately. I did do a bit of cleaning on the CSV to remove some strange characters that were in there for some reason.
Can you tell which one is the original and which one is mine?
