This visualization displays a world map with circles representing missing migrants, where circle size corresponds to the total number of dead and missing individuals. Using React to render SVG marks, the code employs the D3 library's `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` to draw the sphere, graticules, landmasses, and interiors. Data is loaded from a CSV file containing migrant incident coordinates. Circle radii are determined via a square-root scale mapping the “Total Dead and Missing” values.
