{"version":"1.0","type":"rich","title":"React Performance Optimization","description":"This interactive visualization combines a world map and a time-series histogram to explore migration incidents. The map displays circles sized by the total number of dead and missing migrants, while the histogram shows monthly totals, with a brush tool to filter the map’s data by date range. Built with React and D3 v5, it uses `geoNaturalEarth1` and `geoPath` for the map, `scaleTime` and `histogram` for binning, and `brushX` for interaction, with `useMemo` caching to optimize rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/26d7a138117648deb2eb354e1975a022?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
