Abstract: Researchers often need to visualize how policy events evolve, intersect, branch, and diverge over time so they can better understand complex policy processes and identify patterns that may later be linked to macroeconomic or other aggregate outcomes. This is especially valuable when the same policy history can be examined under different analytical lenses, such as narrow sectoral categories or broader policy groupings. In Stata, however, visualizing these interacting event structures is not straightforward from a flat one-record-per-event dataset, particularly when the same data must be repeatedly restructured into alternative views. I propose a workflow that addresses this challenge through flexible subsetting and by organizing events into stages. The workflow allows the same dataset to generate alternative policy process maps efficiently. In the sanctions context, for example, events can be grouped narrowly by sectoral sanctions or more broadly by financial and trade sanctions, revealing different event flows and helping researchers trace how policies connect and evolve over time.
