The D3 bar chart project was my first attempt at using D3 to visualize data. And boy, was D3 more difficult that I expected it to be. I expected a stroll in the park and got a punch in the face! This graph shows one bar which represents US gross domestic product per quarter from 1947 - 2015.
D3 started out simple enough, but using scales and getting my graph to align properly and get everything to display the way I expected was quite difficult. There are still a few rough edges in this bar chart and some of the other D3 projects I worked on.
One of the most useful resources I relied upon for learning D3 and getting the first couple of these projects working was Scott Murray's D3 tutorial.
