We grouped the reports by quadrant, and discarded any that did not have a quadrant specified. ![]() Then we mapped and did an intersect query to find reports that did specify a quadrant but had coordinates that fell outside of that quadrant. We had to try and re-geocode those.Īnother quirk was that in 50 years, streets and addresses can change. We came across several intersections that didn’t seem to exist anymore. This was also a larger issue in general, as we could only map using existing map data-recreating the street grid of 1968 would have taken a little more time than we had for this project. Once we had our data and maps in order, we worked to incorporate them into the narrative, alongside archival photos and video interviews with people who experienced the riots. The goal for this piece was to create a visual timeline of the riots. Not only recounting the events and statistics of what happened, but also giving readers a sense of how D.C. In that regard, the visual elements-maps, photos and videos-were particularly important to the storytelling process. We began by outlining 7 distinct sections of the story and what each would touch on. From there we went slide by slide, identifying potential visuals for each point we wanted to make. This diagram, created by Dan Zedek, Professor of the Practice at Northeastern University School of Journalism, shows the different components we used and how they wove together the past and present. This story format-full screen visuals punctuated by shorter, corresponding blocks of text-evolved from previous stories that the Post Graphics team has worked on, including Raising barriers: A new age of walls and Sin Luz: Life without power. One of our earliest visions for the piece was to animate the Secret Service reports as time advanced in the map to show the impact-both physical and mental-of the unrest sweeping across the city. ![]() We used Mapbox’s data-driven styling to create rules that update the opacity and radius of the reports, giving the circles an expanding fading circle effect. The digitized building damage for the entire city was included as a separate polygon layer as well, using colors similar to those used in the 1960s maps we originally digitized the data from.
