{"version":"1.0","type":"rich","title":"migrants on map","description":"A choropleth-style map displays migrant deaths and missing persons, with circles sized by the count of dead and missing. A linked histogram below shows the same data over time, allowing users to brush a date range to filter the map. The visualization uses React with D3 v6, including `scaleSqrt` for circle sizing, `geoNaturalEarth1` and `geoPath` for the map projection, and `brushX` for the range selection. Data comes from a CSV of global missing migrants.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/01ed289069fd4945845419ea10069e2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
