{"version":"1.0","type":"rich","title":"Missing Migrants (part 7) : Optimizing performance","description":"A dashboard maps migrant deaths worldwide alongside a time-series histogram, with a linked brush filtering the map’s circles by date range. Built with React and D3 v7, it uses `geoNaturalEarth1` and `geoPath` for the map, `scaleSqrt` for circle sizing, and `brushX` for interactive filtering. The histogram aggregates monthly totals via `bin` and `timeMonths`, with axes rendered from `scaleTime` and `scaleLinear`. Data comes from the Missing Migrants Project CSV, with geographic boundaries from TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b5a44e5bb1f4c908854b436c031ad8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
