This React visualization combines a natural Earth projection world map with migrant death and missing person data, plotted as scaled circles whose radius encodes the total count. A linked histogram below displays the monthly distribution of deaths, featuring a brush filter that dynamically updates the map’s displayed points based on the selected date range. The code uses d3.geoNaturalEarth1, d3.geoPath, d3.geoGraticule, d3.scaleSqrt, d3.bin, d3.brushX, and d3.timeMonths, rendering SVG elements with topojson world atlas data and CSV migrant records.
