This visualization combines a world map bubble chart with a time-series histogram to display missing migrants data. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with circles sized by a square-root scale (`d3.scaleSqrt`) representing total dead and missing per location. A date histogram below, built with `d3.bin` and monthly thresholds, aggregates the same metric over time. Data comes from a CSV dataset of missing migrant incidents, rendered in SVG within a React framework using D3 v7.
