Fork of Migrant Deaths Linked Views with Fast Brushing
This example links a geographic bubble map of New Jersey counties with a time-series histogram, using color and size to convey the annual salary of migrant deaths. Brushing the histogram filters the map, with the selected time range visually isolated on the map. The visualization is built with React and D3 v5, using `d3.geoMercator` and `d3.geoPath` for the map projection, `d3.scaleSqrt` for bubble sizing, and `d3.brushX` for the interactive filter. Data on migrant deaths and county boundaries are loaded from CSV and TopoJSON sources.
