{"version":"1.0","type":"rich","title":"Chess Federation Transfers with Brushing","description":"This visualization combines a world map of missing migrant incidents with a brushing-linked time histogram. It uses D3’s `geoNaturalEarth1` and `geoPath` to render country boundaries and graticules, while circle size reflects death tolls via `scaleSqrt`. A `brushX` interaction filters the map by date range selected in the histogram. Built with React and D3 v5, the data comes from a CSV of global missing migrants, with the map optimized through `useMemo`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f9ec6115bcfe4fb99ccefe7740a95716?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
