{"version":"1.0","type":"rich","title":"Map Brushing","description":"This example links a world map of missing migrant incidents to a brushing-linked time histogram. The map displays circles scaled with `d3.scaleSqrt` based on total dead and missing counts, projected using `d3.geoNaturalEarth1` and rendered with `d3.geoPath`. A brushed time range filters the map’s circles in real time, using `d3.brushX` and `d3.histogram` to bin monthly totals. The React app uses `useMemo` for performance, with data sourced from a CSV of missing migrants and country boundaries from World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d42182a5508044069717b4789d873ee1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
