{"version":"1.0","type":"rich","title":"Streamgraph with Brushing","description":"A choropleth-style bubble map of global migrant deaths and disappearances sits above a brushing-linked date histogram. The map projects circles scaled by death counts using `d3.geoNaturalEarth1` and `d3.geoPath`, drawing land, graticules, and interior borders from TopoJSON. Brushing the histogram’s `d3.brushX` filters the map’s circles in real time. The histogram aggregates reported dates into monthly bins via `d3.bin` and `d3.timeMonths`, with axes built from `d3.scaleTime` and `d3.scaleLinear`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d115f58de764f19b8bb373561a11202?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
