{"version":"1.0","type":"rich","title":"Missing Migrants Combo Viz","description":"This combo visualization displays global migrant deaths and disappearances through two coordinated views. A world map using `geoNaturalEarth1` and `geoPath` projects circles scaled by `scaleSqrt` to represent cumulative fatalities per location, while an overlaid histogram uses `scaleTime`, `bin`, and `timeMonths` to aggregate the same data by reported date. React manages state through hooks, with D3 v6 handling data loading via `csv` and `json`, and the TopoJSON `feature` and `mesh` APIs rendering land and borders. Circle opacity and axis styling are defined in CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cff3144174c14e04baf54fdc8900048b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
