A choropleth-style bubble map displays missing migrant incidents worldwide, with circle size scaled by total deaths and missing persons using d3.scaleSqrt. A linked date histogram beneath the map uses d3.brushX to filter the map's bubbles interactively by date range. The visualization renders with d3.geoNaturalEarth1 and d3.geoPath for geographical features, while React hooks manage state and data loading from a CSV of Missing Migrants statistics.
