This visualization maps the history of U.S.–North Korea nuclear negotiations from 1990 to 2012 using a timeline of event annotations overlaid on a stacked bar chart. The chart displays monthly counts of provocations and negotiations from USKoreaData.csv, with a second layer of detailed event descriptions from Negotiations.csv appearing as labeled annotations at their corresponding dates. The stacked bars encode two variables—Provocations and Negotiations—with the height of each bar segment proportional to the number of events that month, and the annotations provide context for major diplomatic milestones such as Six-Party Talks and bilateral meetings. Built with D3 v4 and rendered as SVG, the visualization uses a clean temporal layout with leader lines connecting annotations to the data points, enabling viewers to trace the relationship between negotiation efforts and provocative actions over time.
