{"version":"1.0","type":"rich","title":"dv2020-ep40-viz42 - missing migrants bubble map","description":"A bubble map visualizes global migration incidents from the Missing Migrants Dataset, with circle size encoding the total dead and missing per location. The visualization uses a React component structure with D3’s `geoNaturalEarth1` projection and `geoPath` to render country boundaries, graticules, and shorelines from TopoJSON world-atlas data. A `scaleSqrt` maps data values to circle radii, while SVG circles are positioned via the projection coordinates. Interactive updates are handled through React state and hooks, with data loaded asynchronously via D3’s `csv` and `json` functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea63bcc241ea44669eeefe0582510229?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
