Missing Migrants - Multiple Views with Brushing
A world map and a time-series bar chart display data on migrants who died or went missing, sourced from the United Nations Missing Migrants project. The map uses a `geoNaturalEarth1` projection with `geoPath` to render landmasses, while circles sized by `scaleSqrt` represent casualty counts. A brushing interaction on the date histogram, implemented with `brushX`, filters the map’s circles to the selected time period based on `Reported Date`. SVG elements render both views.
