World Map-Migrant Deaths-Grayscale
A world map displays aggregated counts of missing migrants, with proportional circles marking incident locations. A linked time-series histogram below the map allows brushing to filter the displayed data by date. The visualization uses D3 v5 for map projections and scales, alongside React hooks for state management and rendering. Migrant data comes from a CSV file, while country boundaries are drawn from World Atlas TopoJSON.
