This example combines a bubble map and a date histogram to visualize missing migrants globally. The map uses a natural Earth projection with `d3.geoNaturalEarth1` and `d3.geoPath`, where circle radii scale with the square root of death counts via `d3.scaleSqrt`. Below it, a time-series histogram aggregates monthly totals using `d3.histogram` and `d3.timeMonths`, with bars rendered as SVG rectangles. Both views share data from a CSV file, loaded via `d3.csv` in React.
