{"version":"1.0","type":"rich","title":"choropleth Map","description":"A choropleth map visualizes missing migrant events from the Missing Migrants Dataset, with each circle sized by the total number of dead and missing per event. The map uses the `geoNaturalEarth1` projection and renders land, graticules, and country interiors via `geoPath`. Circle radii are scaled with `scaleSqrt` based on the data values. The visualization loads World Atlas TopoJSON for country boundaries and plots events using d3.csv and React hooks for data fetching.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e2b9f914a72d4f39ac07017cb5e91454?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
