Though I am writing this well after the fact, above you can see the first d3 visualization I have made which can be shared publicly. I completed it as part of the weekly Tableau community project called #MakeoverMonday, and it is the first time I completed one of these projects with d3 instead of Tableau.
In this visualization, I used d3 version 4 to create a responsive bar graph illustrating the total number of spacewalks from the International Space Station in each year from its launch until early 2019, when I completed this project. The data is housed in a CSV and can be obtained from NASA.
Please note that the visualization resizes and even rearranges as you change the size of your browser window, including the hand-coded squiggly path which does not appear if there is insufficient room for it.
