The visualization presents global migrant deaths and disappearances through two linked views: a bubble map and a time-series histogram. Brushing a time range on the histogram filters the map’s circles, which are scaled by the square root of the death count. Built with React, it uses D3 v7 APIs including `geoNaturalEarth1`, `geoPath`, `scaleSqrt`, `brushX`, and `bin`. Data comes from a CSV of Missing Migrants records, rendered as SVG marks over world atlas topography.
