A world map uses proportional circles to show the total number of dead and missing migrants per incident location, with bubble size scaled by d3.scaleSqrt. A separate date histogram below aggregates the same totals by month using d3.bin and timeMonths thresholds. The visualization relies on d3.geoNaturalEarth1 and d3.geoPath for map rendering, with data from a CSV of global migrant incidents. React manages the SVG output, combining both charts into a single interactive view.
