A map and a time-series histogram visualize missing migrant data. The map uses a D3 natural Earth projection (`geoNaturalEarth1`) to place circles sized by the square root scale of casualties at their coordinates. The histogram below bins reported dates into monthly intervals using `d3.histogram` and `d3.timeMonths`, drawing rects scaled by total deaths. Both use `d3.scaleSqrt` and `d3.scaleLinear` within a React SVG rendering.
