This visualization combines a natural Earth projection bubble map with a time-series histogram to show the geographic distribution and monthly totals of missing migrants. The map uses d3.geoNaturalEarth1 and d3.geoPath to render country boundaries, with circle areas scaled by the square root of deaths via d3.scaleSqrt. The histogram below bins reported dates into monthly intervals using d3.histogram and sums the corresponding casualties. Data comes from the Missing Migrants Project CSV, loaded via d3.csv, with React managing the composite SVG layout.
