恐怖主义伤亡数
This visualization combines a world bubble map with a time-series histogram to explore global terrorism casualties. The map displays circles scaled by the total dead and missing, while the histogram shows monthly casualty sums. A brush on the histogram filters the map’s circles interactively. The visualization uses React, D3 v5, and SVG, leveraging `geoNaturalEarth1` for the map projection, `scaleSqrt` for circle sizing, and `brushX` to enable time-range selection. Data comes from the Global Terrorism Database, with country boundaries from World Atlas TopoJSON.
