This interactive visualization combines a geographic bubble map with a time-series histogram to explore records of missing migrants. The map plots incidents using D3's `geoNaturalEarth1` projection, while the histogram aggregates counts by month. Users brush over the histogram to filter the map’s circles in real-time, leveraging D3’s `brushX` and React state for synchronized updates. Data is loaded via `d3.csv` from a published subset, and the rendering uses SVG with React components.
