{"version":"1.0","type":"rich","title":"Test","description":"This interactive visualization maps the global distribution of missing migrants, using bubble size to represent the total dead and missing per location. A linked time-series histogram below the map allows filtering by reported date, with the map’s bubbles updating in response to the brush selection. The map uses a natural Earth projection rendered with `d3.geoPath` and `d3.geoGraticule`, while the histogram applies `d3.histogram` with monthly bins. The React implementation leverages `useMemo` for performance, with data loaded from a CSV of the Missing Migrants Project.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a6c68d89c8e948d9922c93318702fc02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
