World Map Multiple Views with Brushing
This interactive visualization presents a world map of cities with populations over 50,000, using bubble size to encode the number of dead and missing individuals. A linked date histogram below the map displays the same data aggregated by reported date, with brushing enabled to filter the map. When users brush a time range in the histogram, the map updates to show only cities with reported incidents in that period. The map uses a Natural Earth projection with graticules and country boundaries, while the histogram bins data by month and sums the dead and missing counts. The brushing interaction between the two views allows users to explore temporal patterns geographically.
