While going through my agenda for last year, I noticed that there were way more international observances than I thought. There’s a list of those on Wikipedia.org, so I decided to visualize it !
I chose to arrange the days of the year in a spiral to show the total number of observances. It is arguably not the best visual device to easily find a specific day, but it works well to show the total quantity (which was my intention). This work was also an opportunity to link as many interactive elements together to facilitate exploration.
