Migrant Deaths Linked Views with Brushing
A choropleth-style bubble map shows migrant deaths by location, with a linked time-series histogram below. Brushing the histogram filters the map circles in real time, revealing temporal patterns. The visualization uses React with D3 v5 APIs including `geoNaturalEarth1`, `geoPath`, `scaleSqrt`, `brushX`, and `bin` for monthly aggregation. City coordinates and death counts come from CSV data, while country boundaries use TopoJSON from World Atlas, rendered as SVG with graticules and polished styling.
