A bubble map and histogram visualize the Missing Migrants Dataset, showing the geographic distribution and monthly counts of dead and missing migrants. The histogram uses a brushing interaction via `d3.brushX` to filter the map’s bubbles by date range. The map is rendered with `d3.geoPath` and a natural Earth projection, while data is loaded through `d3.csv` and world map topology via `d3.json` with TopoJSON. The React-based interface uses D3 scales and SVG elements for rendering.
