This visualization combines a world map and a time-series histogram to explore global migrant deaths and disappearances. Brushing a date range in the histogram filters the circles on the map, which use `d3.scaleSqrt` scaling and `d3.geoPath` with a `geoNaturalEarth1` projection. The histogram bins monthly data with `d3.bin` and `timeMonths`, while the brush uses `brushX`. Data comes from a CSV of the Missing Migrants Project, overlaid on a TopoJSON world atlas.
